Now I would like to discuss the progress we made with several aspects of our business in the second quarter. First, I talked about the user metrics and also traffic. In the second quarter of 2022, we continue to achieve high quality and efficient user growth through optimizing our strategies, algorithm content operation, et cetera. We delivered a record high DAUs of 347 million at an accelerated growth of 18.5% year-over-year, which -- with the lower acquisition and maintenance cost per DAU.

On a content side, we're continue to strength in operations in our larger [indiscernible] vertical, while conducting more corrective screenings and opera operations of blockbuster contents.

We further accelerated the growth of our short play content, and achieved meaningful result by any new categories, including [indiscernible] documentary and exploring new duration format, such as 5-minute episodes. Also, DAU is to place great emphasis on content and less on production, particularly on the scripting stage. This strategy has considerably produced blockbusters. Short plays have also contributed a significant user acquisition and user activeness, especially among young and female users.

With key impact into blockbuster content and also stronger operational capability. We recently create a several blockbuster entertainment content. Kuaishou insists on a strategy of providing entertainment content with high directions and premium user experience.

This concludes my prepared remarks. And now I'd like to ask the CFO, Jin Bing, talking to you about financial [indiscernible].

[Bing Jin, executive]

[Interpreted] Thank you, Yixiao, and hello, everyone. We now could have a closer look at the financial performance for the second quarter of this year. So first of all, I'm sure that Kuaishou made a breakthrough progress in the second quarter. Despite a challenging macro environment, our traffic and revenues continue to grow steadily. Meanwhile, our domestic business became profitable at the operating level, and also 2 points ahead of traffic. We also achieved positive results in monetization of overseas business and penetrate our revenue growth achieving narrow operation loss.

Our revenues for the second quarter increased 13.4% year-on-year to CNY 21.7 billion. The increase was mainly driven by revenue growth in our online marketing services, e-commerce business and live streaming business. Revenue from online marketing services reached CNY 11 billion in the second quarter of 2022, up 10.5% year-over-year. This was primarily attributable to our traffic growth and the continuous improvement in our services production base and ad performances, which continually increased the number of advertisers. Meanwhile, as our solid closed-loop ecosystem generates improved conversion rate. For e-commerce, merchants, their contribution to our closed-loop bond and marketing services show stronger resilience and growth. Other services revenue for the second quarter of 2022 increased by 7.1% year-on-year to CNY 2.1 billion largely due to the solid growth in e-commerce revenues.

Our rich merchandise supply was powered by the growth of well-known bank such as Kwai Brands, which while our enhanced merchant efficiency promoted to increase in the monthly active e-commerce main users. This, combined with our unit trust-based e-commerce model and empowerment by service providers and our total e-commerce GMV to increase by 31.5% year-over-year to CNY 191.2 billion. In the second quarter of 2022, revenue from live streaming grew by 19.1% year-over-year to CNY 8.6 billion. This was primary attributable to improvement in both our live streaming, content quality and platforms live streaming operational capabilities, and also as well as the continuous improvement in user content merchant efficiency, which [indiscernible] growth of average live streaming MPUs of 21.8% year-year to 54.2 million. Our cost of revenues for the second quarter of 2022 increased by 10.9% year-over-year to CNY 11.9 billion, [indiscernible] year-on-year increase was made due to 2 reasons: plus an increase in revenue sharing costs related to ad, which were in line with our revenue growth. Second, the increase in content cost as part of the other cost of revenues resulting from our continued efforts in diversifying content verticals and [indiscernible] content ecosystem.

However, during the quarter, we were able to partially offset the impact of these actives by optimizing efficiencies of our bandwidth usage and reducing our bandwidth expenses and serving custody costs. Gross profit for the second quarter of 2022 reached CNY 9.8 billion, growing 16.5% year-on-year. Gross profit margin in the second quarter of 2022 was 45% improving from 43.8% in second quarter of 2021, an increase of 3.3 percentage points quarter-over-quarter. Our year-on-year increase in GP margin was primarily as a result of further optimize [indiscernible] and server efficiency which drove the decrease in ratio of bandwidth and depreciation to revenue. However, a quarter-over-quarter improvement to gross profit margin was mainly due to optimization of revenue sharing costs and related taxes, selling the marketing expenses were CNY 8.8 billion for the second quarter of 2022 decreased by 22.2% year-on-year, and 7.7% quarter-over-quarter representing 40.4% of revenues, a significant decline of 18.5 percentage points from 58.9% in the second quarter of 2022. This decrease resulted from our improved acquisition efficiency and optimization in content algorithm and operations, which led to more disciplined and efficient standing to our user acquisition and main channels while sustaining strong traffic growth.

Administrative expenses for the second quarter of 2022 were CNY 960 million, increased by 10.6% year-over-year, primarily due to an increase in share-based compensation expenses. Research and development expenses in the second quarter of 2022 were CNY 3.3 billion, decreased by 16.1% year-over-year and 6.8% quarter-on-quarter, primarily due to decrease in employee benefit expenses, including the related share-based compensation expenses. Our operating loss for the second quarter of 2022 continue downward trend [indiscernible] CNY 3.1 billion, an improvement from CNY 7.2 billion in the second quarter of 2021 and CNY 5.6 billion in the first half or in the first quarter of 2022.

As a result, our operating margin increased by 23.6 percentage points year-over-year and 4.7 percentage points quarter-over-quarter, improving from net of 37.7% in the second quarter of 2021 to an active 14.1% in the current coming quarter. Adjusted net loss for the second quarter of 2022 was CNY 1.3 billion, barring substantially from CNY 3.7 billion in the first quarter of 2022 and CNY 5.0 billion in the second half of 2021. This resulted in adjusted net profit margin improvement from net 26.2% in the second quarter of 2021 to net 6% in the second quarter of 2022, representing an increase of 20.2 percentage points year-over-year and 11.7 percentage points quarter-over-quarter. We remain a healthy balance sheet with cash and cash equivalents, time deposits restricted cash and wealth management products of CNY 41.26 billion as of June 30 of 2022.

Going forward, we will continue to reinforce the monetization viabilities of our various business while embracing change and adapting to evolving macro environment with a steady perhaps commitment to sustainable growth and profitable improvement to our group level. We will enhance our operational efficiency and effectively execute our long-term development strategies.

This concludes our prepared remarks. We are now going for questions. Operator, please go ahead.

[Operator]

[Foreign Language] [Interpreted] [Operator Instructions] The first question comes from the line of Alex Poon from Morgan Stanley.

[Chun Poon, analyst]

[Foreign Language] Congrats on a very strong quarter. My question is related to our e-commerce business. Second quarter GMV grew -- growth was much better than expectation. And can management explain it -- describe to us how our e-commerce ecosystem developing so far? And how will we tackle the changes after the COVID for the consumer behavior change?

[Bing Jin, executive]

[Foreign Language] [Interpreted] Thank you for the question. In the second quarter, we continue to build our trust base experience-centric e-commerce ecosystem and speed up improving sales conversion by leveraging live streaming as the main venue. Trust is the cornerstone of our e-commerce system. And also as we continue to improve our user rights and interests protection system and a penetration of orders under the trust purchase, which is part of a system further increase. In particular, our high compensation policy, 9x refunds for each take item now for this more than half of orders, which is [indiscernible] and we are confident to further improve it. With further enhanced platform governance and also presented user feedback as very points in a purchase process in the form like Repeat Customer Recommendation Index and to further strengthen the users company in merchants and our platform.

We continue to lead the industry in e-commerce monthly repeat purchase rate, which had increased both quarter-over-quarter and year-over-year.

These private domains is the foundation of the merchants to operate effectively over time on Kuaishou, our public domain traffic can help merchants quickly get through the [indiscernible] This quarter, we focused on enhancing on conversion rate, up other domain traffic by enriching and refining products and user tax and improving the accuracy of merchant merchandise and users for any period, the GPM of public domain e-commerce live streaming increased by high double-digit percentage points year-over-year and continue to grow quarter-over-quarter. By offering high-quality merchandise and services to strengthen the peak purchase and private domain traffic conversion, we have created a highly efficient dual-engine model with public and private domain.

Also, our e-commerce business will not have to achieve better-than-expected growth this quarter without our continued expansion in high-quality resources on our supply side. During the first half of 2022, the number of monthly new merchants increased significantly by more than 90% year-over-year. More and more merchants gradually recognize the value of live streaming e-commerce, likely [indiscernible] interactions, helpful as this higher conversion rate. We are also actively expanding our rich to high-quality margins in inventory zones. And also our plan is to deploy services in 100 [indiscernible] zones by the end of this year. And at the end of first half, we were over halfway there with more than 10 industries covered.

On the brand supply side, we continue to promote more brands, particularly Kwai Brands to provide consumers with more abundant high-quality merchandise while further enhancing user awareness of brands to our platform in the second quarter. The number of monthly active brand merchants more than doubled year-over-year. Among the internationally renowned beauty and Cosmetics brand achieved average [indiscernible] GMV of CNY 200 million in the first quarter of online platform. And during the [ 618 ] shopping festival, our total brand GMV increased more than 5 folds year-over-year. In terms of Kwai Brands, the number of monthly active Kwai Brand merchants doubled quarter-over-quarter. In addition to our presence in apparel and cosmetic categories where live stream e-commerce holds an advantage. Kwai Brands also featured in categories such as food and beverages, home appliances, [indiscernible] and also other products.

And as for the second part of the question, given the pandemic resurgence in many places in the first half of this year, with their offline operations under pressure, many merchants were more willing to explore online sales channels. At the same time, the pandemic also filled the desire of traditional online merchants to find new growth channels even as the leverage to speed up since signing up new merchants. So this year, we continue to strengthen our support for start-up merchant, establishing an exclusive traffic pool and providing them with diverse products and marketing tools and the one-on-one operation services. Furthermore, our service providers are providing more topic services to drive new merchants [indiscernible] points, and also in relation to product selection and also operation at the early stage, helping them jump starting and also achieving GMV growth.

In the second quarter, the next month retention rate of the new merchants increased significantly year-over-year and quarter-over-quarter both and also the time between [indiscernible] of new merchants short term by nearly 15% year-over-year.

In addition, we could see us as being more price-sensitive and more rational in the post-pandemic era, which resonates well, whether on staple quality good and reasonable prices philosophy. So we bring more exposure to merchants, capable of providing a high-value expense ratio, and this encourages merchant to refining their products and services. At the same time, we continue to improve the quality of product fulfillment and aftersales services.

So our consumers can buy affordably and also the trust of new products. So although effected by the pandemic and the unnecessary consumption overall was at best. During the 616 promotion. We noticed beauty and cosmetics also the home appliance within other categories on quite show managing a relatively healthy recovery.

Furthermore, consumers staple service, such as food and beverages saw rapid development during the pandemic. Although in the food and beverage vertical, the penetration rate of livestreaming e-commerce is still rapidly low. We believe there is a great upside potential with the streamers providing expression and also rigidity of to pay and flavor as well as the bulk sales made.

As a trust-based e-commerce platform with fast expanding traffic advantage. Increasing matching efficiency and also the product supply, we believe standard products also have much room for penetration to our platform. We are stepping up our effort to develop shopping more like functions, including quiet shops, entry point, search box and also get what you like feature, which can help users who have a clear shopping target to find where exactly to get it, better catered to users with brief purchase demand and keep reinforcing their purchasing on Kuaishou. We believe, in the near to long term, the total GMV of the live streaming e-partners industry centered on short video platforms can reach CNY 6 trillion, and we will continue to strengthen our leadership in this industry.

[Operator]

[Foreign Language] [Interpreted] Next question comes from the line of Thomas Chong of Jefferies.

[Thomas Chong, analyst]

[Foreign Language] May I ask management that we think of operational efficiencies and ROI uphold on investment, how should we think about our top line growth, and achieve effective results?

[Bing Jin, executive]

[Foreign Language] [Interpreted] So thank you for the question. It is indeed a very exciting our domestic business growth even 2 quarters ahead of schedule. We made efforts on several fronts' revenue growth, gross margin. To begin with, while maintaining steady revenue growth, we made breakthroughs in our revenue-sharing cost management as our core business grew in scale and influence, we innovatively design and optimize a more effective revenue-sharing mechanism, lowering the revenue-sharing costs and also related taxes as a percentage of revenue by 2.5 percentage points quarter-over-quarter.

Secondly, upholding the principle of using technology to higher efficiency and with efficiency, keeping costs under control, we focus on tech upgrades to achieve the ultimate in cost effectiveness. In terms of server technology, we advanced the dedicated management of resources and implemented the technological innovations, which improved computing and storage resources utilization rates, helping us to minimize the unit resource costs.

In the first half of the year, while the total domestic time spent grew by over 40% year-over-year, our bandwidth costs per 1,000 units in China fell significantly year-over-year. So the ratio of bandwidth and server costs to revenue dropped by over 3 percentage points, and that contributed markedly to our overall gross margin improvement.

As for audio and video technologies, we carried out a vast technology research and developed applications, which combined with multiple video product algorithms, image enhancement and audio compression algorithms, reduced considerably our total bandwidth usage. Our self-developed product algorithm [ KBC] is the industry's first next-generation video algorithm standard, widely promoted and used online, and also the large-scale launch of [ PCBN ] and other device cloud interaction and integration technologies have substantially increased the promotion of free and low-cost bandwidth usage.

And regarding expenses. In terms of selling and marketing expenses, since the third quarter of last year, while ensuring user growth we have been able to keep lowering the acquisition and retention costs per DAU through organizational restructuring, efficiency enhancements and technology iterations.

We also strengthened refined management of our operations plus competition, eased compared with last year. In the second quarter, with rapid traffic growth maintained, and also user number reaching a new high, selling and marketing expenses as a percentage of revenue declined by 18.5 percentage points year-over-year.

And lastly, we continue to optimize our personnel-related costs to revenue ratio through a series of organizational restructuring and efficiency and cost initiatives, moving closer to the industry-leading level. At the concerted efforts of all in the company, we notably narrow our losses. We will continue to explore more monetization models and improve the monetization efficiency where -- while following an efficient growth path to increase revenue while reducing costs, and also which will give us a solid foundation to unlock the value in the medium to long term.

[Operator]

[Foreign Language] The next question comes from the line of Kenneth Fong of Credit Suisse.

[K. Fong, analyst]

[Foreign Language] Congrats on the strong quarter. I have a question about client recruitment. Can you update us on the latest progress growth strategy as well as the plans for monetization?

[Bing Jin, executive]

[Foreign Language] [Interpreted] Thanks for the question. First, China's blue-collar population exceeds 450 million, accounting for half of the country's working population, and are the most in-demand workers in the country. With the population bonus commission and also the labor shortages at rise, the blue-collar recruitment market has become supply or user unit. However, we have noticed that in the past.

These users have not been adequately searched and blue-collar recruitment market has many pain points such as inadequate access to information, false information and consistent contract performance, quality, et cetera, et cetera. And for employers, they also face challenges that require urgent attention, such as low recruitment conversion rate, high recruitment costs and also core economies of scale. In the post-pandemic year, we have spotted opportunities in blue-collar recruitment, also, as the most favorite show video and live streaming platform of blue-collar users, we see it as our responsibility to step up and deliver better solutions to industries given superior user experience to blue-collar workers and higher conversion efficiency to enterprises.

I'm quite sure of advantages of online blue-collar recruitment efficiency and experience are primary built on our 3 core competencies. The first one is the scale of our user base. In the second quarter of this year, the unit MAUs of required equipment reached 250 million, making an online blue-collar recruitment platform with the largest user base here in China.

Equally important is the impact of our user base on the business conversion model. Compared with daily recruitment for entertainment current consumption, job hunting is a low-frequency user behavior. As blue-collar workers change jobs 3 to 5 times a year for conventional recruitment platform, users will only store the app for the app to become idle after a job is found.

So constantly, a larger budget has to be used on user acquisition and eventually recruiters payable for higher operations and traffic costs. However, [indiscernible] Kuaishou, our rich short video and also Latin content play a crucial role in driving user acquisition and attention earning on this advantage. We provide recruitment services effectively improving [ EMV ] operating efficiency while also lowering recruitment costs for enterprises.

And the second factor is our ability to build trust. Trust is absolutely critical in blue-collar recruitment. Taking the secondary as an example, 80% of the blue-collar job seekers are job hunting across provinces. Considering the impact of the pandemic, it is very important for these job seekers to have a better understanding of potential employers and also positions so that they can save relevant expenses.

And also the interactive model of Kuaishou livestreaming allows users to obtain critical information such as work environment and job content while establishing trust with live streamers and employers. Such trust-based real-time interactive job-hunting experience cannot be codified by traditional search experience or job listing.

In addition, since live stream has accumulated a valuable user asset on Kuaishou we are motivated on other service agreements for offline stages of recruitment process.

Kuaishou also provide users with a complaint channel. Our long-term operation mindset and trust-based model gradually cultivates it through the mutual trust and public supervision, provide recruitment experiences and conversion rate far exceeding the traditional darkening model, and also ultimately reduce the patch of false information and fraud again uses joint contract fulfillment offline.

The third advantage is our distribution and matching capability with advanced and diverse traffic. Kuaishou excels in nationwide traffic distribution. Our efficient traffic matching and the economies of scale make us well suited for large-scale and rapid blue-collar equipment. Our industrial leading MMU technology is capable of deeply understanding the multimedia content, which combines with user characteristics, recognition enables better recruiting cold staff of data.

In addition, we introduced algorithm technology to precisely match supply and demand while also boosting public domain traffic allocation thereby improve both number of views and successful conversion rates. There -- and also ultimately build a highly efficient, accurate and authentic service chain.

From recruiter's feedback, our placement conversion rate is very competitive in the industry, and we are one of the most effective longterm options for enterprises. In summary, the advantages of our vast business model, the real-time interactive nature of livestreaming and the trust factor deeply embedded in our DNA has lowered the job finding threshold for blue-collar workers and increase the recruitment conversion rate for enterprises.

We recently made some key milestones in the equivalent business and also have some obligations. In June of 2022, the half year seems quite equivalent when launched. The peak number of daily resume submitted reached a high of over 360,000, and also assuming rather quickly the second place in the industry, being it there.

However, the resources that we have invested in products and research related to the businesses considerably less members of other blue-collar recruitment platforms. Furthermore, as units grow, so our brand recognition and voice in the blue-collar equipment industry, increasing number of enterprises, agencies and livestreaming who are actively seeking cooperation with Kuaishou and even relocating the focus of business under Kuaishou conducted to producing a flywheel effect as well as building a moat for defending user mindset and relevant content.

At the end of June, we had more than 100,000 corporate partners. Meanwhile, we have noticed that our blue-collar equipment business and our platform's core consumption indicators are trending in the same direction. This shows that our industrial content such as blue-collar recruitment had a good extent, satisfying user's regular needs and in turn encouragement to make Kuaishou their preferred platform. And as such, we have reached the cross-business synergies.

On monetization, we've initiated small-scale trials of advertisements and achieved promising initial results. We are also exploring more in-depth monetization models. This year, we will continue to refine our operations and content, expand the scale of job applications, improve traffic utilization efficiency and test our business models.

We expect the online penetration rate of blue-collar equipment to reach 30% in 2025 or '26, and the market side to reach around CNY 100 billion. We hope to capitalize on our advantage to enhance the recruitment experience for the entire industry while improving online conversion rate and capturing a leading share of CNY 100 billion online blue-collar equivalent markets.
