Thank you, Steven, very good questions. Let me just answer first and see our CEO will have any further points to add, which just for the take rate, you are correct. If you just use a lump sum number to calculate a take rate. The gross take rate will decrease a little bit in the second quarter. The key reason is not because of the guarantee liability or the cost. That's because what I just mentioned we originate, we have used this capital-light model that will decrease the economic with we are more the whole book is health, more healthy. So if you take that capital-light model out the traditional model, take rate, relatively stable, okay and actually it slightly going up a little bit.To answer your second question. First of all capitalized model is not ABS, okay. It's just -- it's a pure for us as a pure technology services. We basically help the financial institution to find the customers do the preliminary risk analysis and help them do these post organization collections and other services.The only difference between capital-light model and the traditional model is we don't take any credit risk, and financial institution will take all the credit risks, okay? So it's not an ABS issue. So we don't see any regulation hurdle for that portion. So going forward, in the long run, we don't have number yet, but we are very confident to increase that portion significantly, as long as the financial institution are willing to take that.And for the third question, acquisition cost. Yes, it continues to grow up, growing up as I just, in my remark, I just mentioned that primarily due to the competition landscape, but we still see that as a long time investment, and so as long as the return on investment for the customers are sound and attractive, we will continue to do that. And as I just mentioned, for the first long slowdown, we can easily breakeven for all the cost. So we don't see any reason to stop this long-term investment. And maybe Haisheng will have something to add on the previous questions.
