We are pleased to announce that Sunlands Technology Group had a very strong opening quarter for 2021, starting with net revenues that rose to RMB 694.3 million, a 22.9% year-over-year increase. The increase in net revenues with many driven by the year-over-year growth in gross billings since the second half of 2020. Gross billings in the first quarter rose to RMB 593.7 million, representing year-over-year growth of 14.9%. In terms of new enrollments, we achieved a 107.6% increase year-over-year, which surged to over 145,000 students.

Because of this strategy, gross billings in master's degree oriented programs [indiscernible] a gross return of 73.6% year-over-year and contributed approximately 34% to total gross billings compared with 22% in the same quarter last year.

Thank you, Tongbo Liu. Hello, everyone. We are pleased to see our first quarter net revenues beat guidance once again and hit a record high, as rising brand recognition for our master's degree oriented and professional skills programs bolstered our top line growth momentum. Our ongoing diversification from STE programs and our commitment to optimizing student experience affirms our confidence in sustaining this momentum. We also managed to lower costs, delivering 52.2% and 16.3% reductions in G&A and R&D expenses, respectively. As a result, first quarter net loss narrowed 18.7% year-over-year to RMB 53.3 million. As we look ahead, our marketing department will continue to explore avenues to promote brand awareness, while our sales team will target a higher referral rate and sales conversion rate to fuel future growth. And most importantly, our management is keeping an eye on implementing optimal strategies that deliver the best returns for all shareholders. Now, let me walk you through some of the key financial results for the first quarter of 2021. All comparisons are year-over-year and all numbers are in RMB unless otherwise noted. In the first quarter, net revenues were RMB 694.3 million, an increase of 22.9% year-over-year. The increase was mainly driven by the year-over-year growth in gross billings since the second half of 2020. Cost of revenues increased by 9.8% to RMB 106.4 million in the first quarter of 2021 from RMB 96.9 million in the first quarter of 2020.

Our next question comes from Phoebe Chen [ph] from CDC Capital [ph].

My first question would be can you please kindly provide the breakdown of STE and MBA [indiscernible] business and other certificate sector. The second would be that why – the reason gross billing is lower than net revenue from Q1?

Maybe I can answer your second question first. Because we precollect all the gross billing from the students, but we need to record the revenue during the series period. So, that means our revenue will not equal to the gross billing all the time.

From the previous quarter – because we know that – as you said, the precollect nature of education sector, that's why gross billings always higher probably than net revenue and that is what we observe from the previous quarter.

Yes, let me finish my answer. So, the speed to recognize the gross billing quite depends on our mixture of our products. You can say during the past several quarters, the percentage of certificates and MBA will get higher and higher and that the service period of these two categories are much shorter than the STE. That means, with the time when the development of this structure changes, the recognition period will be shorter. That means faster. That's why our revenue now is greater than the gross billing.

Could you repeat your first question? Sorry.

It's a breakdown of revenue or gross billing of different business sectors.

It's quite similar to the first question. Our gross billing structure, I can repeat. The structure from the percentage of STE account for 24% and MBA account for 33.8%. And the third category account for 41%. That's for growth. You mean the revenue? The second is revenue percentage?

Right.

The revenue, STE accounts for 60%. That means that comes from the gross billing of last, maybe the [Technical Difficulty].

Pardon me, ladies and gentlemen. It appears the speaker line has dropped. Please stand by while we reconnect. Thank you for your patience. Pardon me, everyone. We have reconnected with the speakers. Please go ahead.

Sorry for the disconnection. Can you hear me from the – I will continue to answer the first question from CDC Capital. About the structure of net gross billing and net revenue, I think that question is referred to this angle. And the percentage of STE in that gross billing will be 24%. MBA accounts for 33.8%. And the third one accounts for 42%. And regarding to the net revenue, the structure is different. STE accounts for 60.4% and MBA accounts for 53.8%. And the third one accounts – STE account for 40.8%, MBA account for 22.6% and the third one account 34%.

Showing no further questions, this will conclude our question-and-answer session. At this time, I'd like to turn the conference back over to Yuhua Ye, IR representative, for any closing remarks.

Once again, thank you everyone for joining today's call. We look forward to speaking with you again soon. Good day and goodnight.

This concludes the earnings conference call. You may now disconnect your lines.
