third quarter 2021. Please be reminded that all amounts quoted here will be RMB unless stated otherwise. For this quarter, our total revenues were 1,105.5 million, representing an increase of 43.7% year-over-year, primarily due to the rapid growth of our major business lines. Revenues from on-demand delivery solutions were 1,047 million, representing an increase of 38% from 758.8 million in the third quarter of 2020, primarily due to the increase in the number of delivery orders were fulfilled as a result of the industry growth as our continued penetration and expansion into new geographic markets. Revenues from mobility service solutions consisting of shared bike maintenance, ride hailing, and the freight service solutions were 34.6 million, representing an increase of 364.5% from 7.4 million in the third quarter of 2020, primarily due to our enlarged customer base as a service scope for shared bike maintenance solutions and, uh, the commencement of freight service solutions in July 2021. Revenues from housekeeping and accommodation solutions were 21.9 million, representing a significant increase of 538% from 3.4 million in the third quarter of 2020, primarily because we enlarged our customer base for housekeeping and accommodation solutions to include hotels and the B&Bs following our acquisition of Lailai and the Chengtu Home. Our cost of revenues were 1,055.1 million, representing an increase 53.2% year-over-year, primarily due to our business expansion, which resulted in increased costs, prop- proportionate to our revenue growth as the, the incremental hiring expenses and the higher, and equipment costs to expand the workforce on our platform and to secure additional resources in preparation for the anticipated increased demand of our solutions and our continuous business expansion plan in the first quarter. General and administrative expenses were 56.2 million, representing a decrease of 45.6% from 103.2 million in the third quarter of last year. The decrease was primarily due to the decrease in share-based compensation expenses from 72 million in the third quarter of last year to 9.1 million in third quarter of this year, primarily because we incurred substantial share-ba, share-based compensation expenses in the third quarter of 2020, as we satisfied the performance conditions of our share incentive award upon completion of our initial public offering, offering them. Excluding share-based compensation expenses, general and administrative expenses increased by 51% year-over-year, primarily due to the increase in staff cost, in line with the rapid growth of our housekeeping solutions and the professional service fees and expenditures in connection with our business expansion plan. Our research and development expenses were 6.3 million, representing an increase of 108.9% from 3 million in the third quarter of 2020, primarily due to the incurrence of outsourcing expenses to develop a new SaaS system for our housekeeping solutions, and the increase in staff cost as we enlarged our, our research and the development team. The operating loss was 19.3 million, compared to operating loss of 24 million in the third quarter of last year. Excluding share-based compensation expenses, the adjusted operating loss was 10.2 million, compared to adjusted operating profit of 48 million in the third quarter of 2020. We recorded other income net of 39.2 million, compared to other income net of 32.1 million in the third quarter of 2020, primarily due to the increase in fair value change of investments in mutual funds. We also recorded income tax benefit of 0.8 million, compared to income tax expenses of 15.8 million in the third quarter of 2020, primarily due to the lower estimated annual effective tax rate for the third quarter of 2021. Net adjusted EBITDA was 35.1 million, compared to adjusted EBIT of 85.1 million in the third quarter of 2020. The adjusted net income was 28.2 million, compared to adjusted net income of 61.3 million in the third quarter of 2020. For the balance sheet, as of September 30, 2021, we had cash, short-term investments, and the restricted cash of 257.1 million, and short-term debt of 140.6 million. Now move to our financial outlook for next quarter. For the first quarter of 2021, we expect the total revenues to be in the range of 1,050 million to 1,150 million, representing an increase of 20.6% to 32% year-over-year.

Hi, good morning, good afternoon. I hope everyone's doing well. Um, thanks for taking my questions. Um, first, I know some of the other gig economy companies in China talked about some weakness in consumer demand from both the COVID variant of Delta and then some, some flooding and other macro impacts. Um, or, did you guys see anything similar in 3Q, um, and if so, has any of, have any of those trends normalized for 4Q? <silence> Uh, hi. This is Leslie. And, uh, even though the COVID-19 containment measures across the overall China, we can see we capture the business opportunity, and we have very strong growth. So, compared with our, uh, according to our growth, we consider that the, the market for on-demand delivery and for housekeeping and for mob, for mobility is still very strong. And we expect that the Q4, as indicated by Sandra in the, uh, uh, financial outlook, we're still expanding that there will be huge demand, and we will maintain this growth. Uh, although there will be, uh, like a spring festival followed up by, uh, Q4. So, we mainly focused on the profitability driven in Q4, but we expected that the demand for the service and for the revenue growth is still strong. Thank you. Thanks. Um, and secondly, uh, your gross margins were a little bit under pressure again in 3Q, um, down a bit more from 2Q versus what they were last year. How much of that is one-time in nature from some of the platform expenses you incurred to grow in terms of like, technology and hardware? And then what sort of like, a steady state forward gross margin outlook for 4Q and beyond? Um, I would, I would like to explain, uh, the reason why the gross profit is a little bit, little bit down in Q3. That is because, uh, uh, we, uh, we have recruited a lot of staff, um, preparing for this Q4 because, uh, we already expecting, uh, very strong growth compared with last year. And overall, it's about 80% growth compared with last year. So, for this coming winter, we need to prepare, uh, people in advance, because in this year particularly, in the market, the labor is, uh, more, um, the supply
