Okay. Hello, everyone. Thank you very much for joining us for our first quarter earnings conference call. We had a solid start in 2019, with both revenues and gross billings topping the high end of our guidance. Our first quarter results reflect the successful and consistent execution of our strategies initiatives which focus on our core K-12 one-on-one mass-market program in China's lower-tier places. We continue to streamline our business to focus our resources on providing high-quality programs for the growing K-12 market. Our growth strategy is sharply focused on bringing our programs to China's large and underserved markets in non-tier 1 city. Our live online English offerings are a good match to growing demand in tier 2 and tier 3 cities. We are capitalizing on this opportunity. We are actively marketing our services here and it is working. Our referral rates are growing as evidenced by our expanding gross billings. In fact, in the first quarter, our gross billing from non-tier-1 cities accounted for an impressive 72.8% of our K-12 mass-market one-on-one offerings. This compares to just 63% in the same period one year ago. As we move through the year, a key goal will be to continue to make learning accessible throughout China by bringing out our educational offerings to underserved markets. Based on our model, we can easily leverage our existing programs in these non-tier-1 cities. We have a stable and scalable process in place with our foreign teacher operations in the Philippines to support this growth. With our teacher recruiting, training and management systems firmly in place, as well as strong local government support, we are confident in our ability to scale our teacher sourcing capabilities as we expected. As we expand, in 2019, we will continue to dedicate resources to increasing the accessibility of our courses, improving our exposure and strengthening the quality of our offerings and technology while achieving a balance between growing our top line and improving our bottom-line. So, with that, I will now turn the call over to our CFO, Xu Min.

Thank you, Jack. The diligent execution of our more focused mass market strategy contributed to improve the bottom line and healthy growth in the first quarter. We reduced our non-GAAP net loss by 55.1% to RMB59.5 million from RMB132.4 million in fourth quarter 2018. Our one-on-one business gross billings grew by 37.4% year-over-year, and our overall gross margin reached 67.3%, up from 64.6% for the first quarter of 2018. In addition, gross billing increased by 28.1% year-over-year -- gross profit increased by 28.1% year-over-year to RMB217.2 million. Through enhanced sales training and improving sales capacity planning emphasis on referrals, and prudent cost control and cash deployment, we will spur our opportunity for growth while improving our bottom line. Now, I would like to walk you through our first quarter 2019 financial highlights. Net revenues for the first quarter of 2019 were RMB323 million, a 23% increase from RMB262.6 million for the first quarter of 2018. The increase was primarily attributed to an increase in a number of active students. The number of active students in the first quarter of 2019 was approximately 227,000, a 19.2% increase from approximately 190,000 in the first quarter of 2018. Net revenues from one-on-one offerings for first quarter of 2019 were RMB295.5 million, a 20.4% increase from RMB245.5 million for the first quarter of 2018. Net revenues from small class offerings for first quarter of 2019 were RMB27.5 million, compared with RMB19.1 million for the first quarter of 2018. Cost of revenues for first quarter of 2019 was RMB105.7 million, a 13.8% increase from RMB92.9 million for the first quarter of 2018. The increase was primarily driven by an increase in total service fees paid to teachers, mainly due to an increased number of paid lessons. Cost of revenues of one-on-one offerings for the first…

We will now begin the question-and-answer session. [Operator Instructions] First question comes from the Bo Pei of Oppenheimer. Please go ahead.

Hi, management, good evening. Thanks for taking my questions. I had two questions here. One is we gained pretty good operational leverage in 1Q. And then, could you kind of explain, what was the reason behind that operating leverage gain? And then, should we expect the operating expenses as a percentage of total revenue continue to go down throughout 2019? And then, my question number two is, for your 2Q guidance that actually implies a sequential deceleration of the gross billing, could the management put more color on that? Thank you very much.

Thank you for the question. So, number one, we did see a good leverage -- good operating leverage, because we are working very hard. As we indicated in last few earnings calls, we're working very hard to improve our sales efficiencies. And, in fact, we did achieve that through a lot of operation -- optimization. And so, we believe the key is that we really start to see efficiency improvement in our sales and marketing. And our Q1, non-GAAP sales and marketing expense was 39% of our gross billing for our one-on-one business, much better than 48% in Q1 2018. And we believe we are going to see the benefit of our previous optimization and efficiency improvement measures, and we will continue to improve that. And for the second question, you mentioned that our Q2 guidance indicated a de-acceleration of our gross billing. So, I would say in the sense, yes, from the number we do see, it is slowing down compared to Q1. However, remember, Q1, we are comparing to a relatively weak 2018 Q1 quarter. And so, it is hard to kind of continue that kind of growth. So, we do see our -- because we're seeing continued growth improvements throughout 2019, so, starting Q2 we are comparing to a much better performance in terms of our gross billing. So, we do expect our healthy growth to continue and drive of our non-tier-1 city expansion. And we do expect that as we continue to deepen our penetration in non-tier-1 city, we will see continued growth well improving our bottom-line.

The next question comes from Zhonghai Yu of CICC. Please go ahead.

So, my first question is the same question that how do you see the trend of your user acquisition cost, is it going up or down, like, can you give like brief range like they rose by about 5% over the same time Y-o-Y like this? My second question is about the competitive landscape. While given that we have very unique positioning that we've had in the tier-3 to tier4 cities, who do we see as our main competitors, and how is it going between we and other players?

So, I'll answer the first question and Jack will answer the second question. So, in terms of customer acquisition costs, we're seeing it's quite stable compared to the past few quarters. We did see a slight improvement in terms of our marketing efficiency. And we are seeing kind of a stable conversion cost. So, it is relatively stable throughout the year. And I'll hand over to Jack for the second question.

[Foreign Language]

Okay. So, I’ll translate. So starting 2019, we are seeing trends that the VC market is cooling down. And so, a lot of our competitors are less crazy burning cash to trying to grow their business. So, we have to say, the intensity of competition is much lower, and it's a much healthier environment for us. As you know, many of our competitors, they use North American teachers. So, their price is 3 times of our price. So, we -- our offerings are much more attractive in lower tier cities. So, we can achieve much better penetration there. As you see from the number that 73% of our core business gross billing are from non-tier-1 cities.

I have follow-up questions. So, given that we have very strong capability in terms of teacher recruiting and training and management, when would you see will be the best timing for us to move from Philippines teachers to like European and Western, American student teachers? I know we did have stop our American Academy business, but when will be the best time for we to get back to the game?

[Foreign Language]

So, as we mentioned earlier, one of our core competencies is our teacher management. So, in the Philippines, we have a 1,000 plus full time team working with close to 20,000 Filipino teachers. We also have eight local offices in the Philippines. We're very proud of the teaching quality of our Filipino teachers. And we firmly believe that a key for English study is frequency, how frequently you take your lessons, not where your teachers are from. And we are also very lucky that we're getting support from government of both China and the Philippines, and under the one belt policy. And we believe there is a lot of opportunities for us to continue to build up our core competencies and Filipino teacher operation.

[Foreign Language]

We believe our focus on the lower tier city has been quite successful and we will stick to that.

[Operator Instructions] The next question comes from Roger Parodi of Silverhorn. Please go ahead.

Hi, Jack. Hi, Xu Min. Thank you for taking my question. You have -- actually you have already discussed pretty what I wanted -- the main questions I wanted to ask. But you might still give some color. You were able to decrease the loss very substantially. What was the main reasons to do that? The other thing is, now 73% comes from consumer second and the low tier, not first tier cities, how could you achieve that? Because I think it takes quite a different marketing approach and this thus leads to -- that you could decrease the loss. And then, you have a very impressive margin as well, the gross margin. What is the reason for that?

[Foreign Language]

I’ll translate first. So, let me share why the net loss narrowed down this quarter. So, the first important reason I want to talk about is to gross billing P&L breakeven. So, starting 2Q ‘18, our one-on-one business has achieved gross billing P&L breakeven for 4 consecutive quarters. We explained in earlier earnings call what is gross billing P&L contribution. So, basically what we do is we take the gross billings times the gross margin and then subtract sales and marketing, G&A and R&D to get our gross billing P&L contribution. So, because the revenues are deferred and until the lessons are taken, so we should see positive impact from previous positive gross billing P&L contribution starting this year.

[Foreign Language]

All right. So, next, I’m going to talk about gross margin, which you also asked about. So, here are several fronts we're getting some improvements. So, number one, we did a price increase earlier in 2019. We increased price by 10% to 15%. So, this contributes to our one-on-one in this margin increase. Second, because our American Academy business has relatively lower margin, we actually are seeing a lower mix of our American Academy in Q1. So, that also contributed to some of the gross margin improvement. And third, our small class business also improves as margin from last quarter’s 27.9% to this quarter's 45.7%. So, all these contributed to our margin expansion.

[Foreign Language]

Last but not least is the sales efficiency. As we mentioned earlier, we actually improved our non-GAAP sales and marketing expense as a percentage of our gross billings from Q1 last year, 48% to 39% in this quarter. So, all these sectors contributed to our margin expansion. And we will continue to work very hard on all these fronts to target to continue to decrease our net loss.

Okay, understood. Thank you for that explanation. Do you still hear me, Xu Min?

Yes.

Yes. Okay. Maybe then allow me to ask a quick follow-on question.

Yes, sure.

That’s related to the guidance for Q2. Looking at all these impressive operational improvements, what is the normal growth rate that we could -- that you would see that still allows you to -- it’s a very theoretical question, I leave it up to you, how to answer it. But at what growth rate do you think you can maintain such an operational improvement, such efficiency improvement, and then can continue to grow? I just look at this number right now for Q2, it's probably bit on the softer side. Just give me a bit more confidence that the growth engine is still working.

Yes. So, in terms of the expectation of the growth, I would say, in the near term, we believe the growth will be -- especially the one-on-one growth, we should be expecting similar growth rate to probably last Q2, Q3. Because as we mentioned earlier, we're not putting a lot of emphasis on the gross billing growth. So, as long as we're probably achieving similar one-on-ones business growth as last year, our emphasis still on continue to decrease our net loss.

[Foreign Language]

All right. So, let me translate. So, when we look at our Q2 guidance, it looks less impressive just because we did really great in Q1, and the growth in Q1 looks even better when you remember that we had a really weak Q1 in 2019. So, but we do expect our one-on-one business continues to grow and especially, when you look at year-over-year growth still much stronger than a year ago. And also for the small class business, we are also seeing a decline. And after one year's operation, we do see small class as a great product. And, but it is still looking for its targeted customer segment. So, what we see is that the customer acquisition cost for small class business is still higher than our one-on-one business, very similar to other small class peers. So, it is our target to continue work on the business model to lower our customer acquisition cost and improve unit economic model. And as you see that, as we continue to balance our business model, trying to achieve getting closer to profitability, we will continue to target to grow our business in a healthy way.

Okay, thanks a lot. Makes a lot of sense. Thank you for that, Jack, Xu Min.

Thank you, Roger.
