Hi, Lingyi, thank you for your question on gross margin and the financials. This is Lin. I will take your question. So, first of all, we continue to take rigorous cost control measures and optimize our cost structure. That's why we were able to maintain our gross margin at relatively high level, which is 56% level in the third quarter. And on top of gross margin, actually I want to highlight further that we are also taking initiatives to improve our operating margin as well. So, to cut our spending, actually in the third quarter, we have taken several measures. For example, we moved our headquarter office to a relatively lower rental building in the third quarter. And secondly, we continue to increase AI technology, which enables us to streamline our R&D team and which resulted in some cost savings in the payroll side as well. So, if you take a look at our operating expenses in Q3, although there were temporarily some one-off impact in Q3, because we have to pay some severance compensation, as well as terminating the old lease contract, we need to pay some compensation expenses. So, that hit our third quarter, but that's temporary and that's only a one-off issue. And if you take a long-term view at our these initiatives, those two measures altogether will give us a spending cut of at least RMB30 million on an annual basis. So, that's quite improvement on our operating margin. And going forward, on one hand, we will continue to grow our revenues and on the other hand, we will continue to embrace AI technology to more diversified business scenarios, so to cut our cost and further cut our spending. So, overall, we will improve our gross margin as well as operating leverage. Thank you.
