Hello, everyone.
I would like to thank you all for joining us on today's call. In the second quarter of 2021, we continued to operate prudently across our cash credit business line, maintaining asset quality at a healthy level, which generated approximately RMB 3.9 billion in transactions for our loan book business with an on-balance sheet loan balance of RMB 3.5 billion . Our tireless efforts to maintain a robust balance sheet ensure our ability to safeguard the interests of our shareholders while providing us sufficient funding to propel the development of our extracurricular activities business, Wanlimu Kids. We are pleased with Wanlimu Kids' steady progress. We successfully opened two new centers recently, one in Fuzhou City in Jiangxi Province, and the other in Xiamen. We have signed lease agreement for another 37 Wanlimu Kids centers, of which 24 centers are under renovation.
As we further expand our footprint, we believe our first mover advantages in depth entrepreneurial expertise and strong digitalization capabilities will fuel the ongoing growth of Wanlimu Kids. Now, I would like to turn the call over to Sisi for more details on our results.
Thank you, Min, and good morning and good evening, everyone. Amid complex online lending market dynamics, we maintain our cautious and conservative approach in our loan business by rigorously assessing credit risk in new transactions. The transaction volume for our loan book business was RMB 3.9 billion this quarter. Our asset quality continues to improve with a D1 delinquency rate below 5% at the end of the quarter, and our M1+ delinquency coverage ratio remains high at 2.5x .
Echoing Min with respect to our extracurricular enrichment business, our vision for Wanlimu Kids is to help children joyfully explore their talents and potential in sports, arts, music, and other extracurricular activities. We believe this goal is aligned with the core principle of China's new regulatory framework, which aims to promote students' all-around development. With our existing three centers as well as 37 new centers in the pipeline, we are confident to replicate the success of our flagship center and tap into opportunities in China's fast-growing extracurricular enrichment market.
Together with the opening of new centers, we will incur more operation expenses relating to staff compensation, sales and marketing, rental expenses, et cetera, which would affect our profitability in the third quarter. Looking ahead, we will continue to closely monitor the evolving regulatory environment and proactively respond to policy changes. We believe that with our thoughtful operating strategy in the loan business, along with the Wanlimu Kids' steady progress, we are well-positioned to deliver long-term value to all stakeholders. Now let me share with you some key financial results. In the interest of time, I will not go over them line by line. For a more detailed discussion of our second quarter 2021 results, please refer to our earnings press release. Our total revenues were RMB 412.1 million, representing a decrease of 64.7% from RMB 1.2 billion for the second quarter of 2020.
Our financing income totaled RMB 311.8 million, representing a decrease of 46.3% from RMB 580.9 million from the second quarter of 2020, as a result of the decrease in the average on-balance sheet loan balance. Our loan facilitation income and other related income decreased by 95% to RMB 12.6 million from RMB 255 million for the second quarter last year, as a result of the reduction in transaction volume of off-balance sheet loans during this quarter. Total operating costs and expenses decreased by 90.9% to RMB 89.3 million from the second quarter last year. Cost of revenues decreased by 82.3% to RMB 64.9 million from RMB 366.4 million for the second quarter of 2020, primarily due to the decrease in costs associated with the loan book business and the decrease in cost of goods sold related to the Wanlimu e-commerce platform.
Sales and marketing expenses decreased by 81.4% to RMB 29.1 million from RMB 156.8 million for the second quarter of 2020, primarily due to the decrease in marketing promotional expenses. General and administrative expenses increased by 44.8% to RMB 109.1 million from RMB 75.3 million for the second quarter of 2020 as a result of the increase in staff salaries, primarily relating to Wanlimu Kids business. Research and development expenses decreased by 30.3% to RMB 39.2 million from RMB 56.3 million for the second quarter of 2020 as a result of the decrease in staff salaries. Provision for receivables and other assets was a reversal of RMB 97.4 million compared to a loss of RMB 519 million for the second quarter last year, mainly due to the decrease in past due on-balance sheet outstanding principal receivables compared to the second quarter last year.
Our net income attributable to Qudian's shareholders was RMB 269.9 million or RMB 1.03 per diluted ADS. Non-GAAP net income attributable to Qudian's shareholders was RMB 282.5 million, or RMB 1.07 per diluted ADS. With that, I will conclude my prepared remarks. We will now open the call to questions. Operator, please continue.
Certainly. Ladies and gentlemen, if you wish to ask a question, please press star one on your telephone keypad and wait for your name to be announced. If you wish to cancel your request, please press the pound or hash key. For the benefit of all participants on today's call, if you wish to ask your question to the management in Chinese, please immediately repeat your question in English.
There are no questions at this point of time, I would like to turn the call back to the company for closing remarks. Thank you.
Hey, AJ. I actually heard from our investors that there might be some technical glitches over the phone that they can't hear us clearly. Is there a spare line that you can get connected to? We do the sound check again?
Pardon the interruption. Am I not audible to you, ma'am? Hello? Pardon the interruption.
Hey. Hello.
This is the operator. Yeah. Am I audible to you?
Yes. Loud and clear.
We have our first question from the line of Hannah Han from BOCOM International. Please go ahead.
Thank you for taking my questions. I have two questions. The first one is, what do you think about the 24% cap that is window guidance by some cities consumer financial companies? The second one is, could you give us more color about your new initiatives for your education program and how it's going to develop forward? Thank you.
Thank you, Hannah.
[Foreign language]
Thank you, Hannah, for these two brilliant questions. Let me address it one by one. Regarding the 24% interest rate cap, per our understanding, is a window guidance that is mainly relevant to licensed financial institutions. Local regulators have very different implementation details and timelines on this issue. Given the fact that our profitability will be negatively affected if our interest rates get capped at 24%. Before any concrete interest rate restrictions get enforced on our proprietary lending activities, we will choose to maintain our status quo, that is, we charge at less than 36%. We don't have plans to boost the growth of our credit business before the regulations turn to the promising side. Nevertheless, we will embrace the regulatory changes and promote an orderly and healthy lending market together. With regard to your second question, for our Wanlimu Kids business.
We are happy to say that we have successfully opened three centers so far and 37 other centers with signed long-term lease contracts in the pipeline. Customers are quite satisfied with our superior service offering. The cool thing is, we spend quite some efforts and money in designing and renovating the centers, which in turn become one of our competitive advantage and entry barriers. As a matter of fact, building swimming pools and sports venues indoor require lots of detailed designing, calculation, and advanced construction techniques. To give the investor community more confidence, our first center, which opened in January this year, already passed our internal test of monthly break-even points, outperforming our expectation. If we take out trial programs and associated four areas from the calculation.
For the business as a whole, the financial numbers are still very small and immaterial as opposed to our core lending business, although customer satisfaction is very good. We will certainly be more than happy to disclose the numbers when they become material. Thank you, Hannah. Hope I answered your question.
Yeah. That's very clear. Thank you.
Thank you. Thank you. There are no further questions, I would like to hand the call back to the company for any closing remarks. Thank you.
Thank you, operator. It's very happy to meet everyone online today, if you have any further questions, please don't hesitate to contact our IR team. You can also find our press release and relevant PowerPoints on our IR website. Thank you very much again.
Thank you. Ladies and gentlemen, that does conclude our conference for today. Thank you for participating. You may all disconnect your line. Thank you.
