Okay, Weicheng, sure. I leave the first question to our -- to my colleagues Robin Xu, who will answer you a little bit later in terms of the new product pipeline to be launched in the second half of this year. Let me just address your second and the third questions first. In terms of tax rebate, it is one-off on a quarterly basis, but it will be recurring items on a yearly basis. The thing is, you know, according to the local tax bureaus treatments, they have in order to promote technology spending, they actually allow additional 40% to 50% of your earning expenses in terms of your deductions for the -- for your effective tax rate calculations. So in the second quarter of this year, actually we finished all the applications and the document reviews by our auditor, PricewaterhouseCoopers, which synced the applications to the tax bureau and also all the documentations was satisfactory. So we have already deducted such tax benefits for 2018 in this quarter. Given that we continue to have a huge R&D spending going forward, I do think the relevant treatments will occur in 2019 and 2020 as well. For the interest expenses, you're right. I think, in terms of the HIBOR spread, which charged by the commercial banks will go down gradually, given that after this thing we actually have more bargaining powers or get more commercial treatment from these commercial banks. I think it is relatively, the interest expenses cost increased in second quarter is mainly due to the underlying HIBOR increase, which you can see, of course, at the same time, we also benefit a little bit from this in terms of the interest income as well. But I think, in terms of the spread, the borrowing costs spread on top of the HIBOR, it will definitely continue to go down in the remaining quarters. Now, I hand over to Robin for your first question.
