Thank you, Lingyi for your questions. This is Lin. I will answer your first question regarding the pandemic impact on the business and outlook for this year's profitability. And Mr. Feng will answer the other two questions for you. Yes, just as Mr. Feng just mentioned, the COVID-19 and the macro challenges did have some impact on our later Q1 and first half of Q2 business, especially on some of our enterprise value-added services, there are some off-line events involved where we could see some impact. However, we have taken several measures to mitigate that impact. For example, we hold online plus off-line forums and we utilize the online live streaming forum as well as the short video format to host the forums and the conference for our customers. That's for our enterprise value-added services. Actually, that revenue segment grew 35% year-over-year in Q1, even outgrow the total revenue, that's a very significant growth during Q1. And regarding the advertising business, obviously, that's a major component of our total revenue. That again also increased 13% year-over-year and if you look at the industry average, if you look at those companies who already reported their Q1 results, and if you look into their online advertising, I would say is it's easy to say that most of them have booked an active year-on-year growth. Well, we have a double-digit year-on-year growth. And I think that's thanks to our 36Kr's content strength and brand image that the SMEs as well as big companies, the Fortune 500 companies all comes to us to pursue brand image as well as performance-based ads. With that said, our advertising business is less reliant on the macro economy and more resilient to the cycle. So that's why we think we have a very good result in Q1 and looking into the Q2 and the rest of the year, first of all with the pandemic, the control is lived. Our off-line events, our Enterprise value-added services will come back. And with the macro economy gradually recover, the advertising spending will also come back and we have a lot of initiatives -- for example, the adjustment to the rate card and some more innovative marketing solutions, especially our short-form video is picking up really, really, very quickly. So that gives us confidence that in the second half or in the remaining of the year, we can catch up what's left in the first half is actually in Q2. So we are still, as Mr. Feng mentioned, we are still very cautiously optimistic about the full-year, and we would maintain our forecast for the full-year basis profitability. Hope that answers the question.
