So, for the quarter-over-quarter growth, I think the first thing we want to clarify is right now, our brand portfolio has been changing dramatically. So, we have three years -- we have three brands last year, but now we have seven brands. And in skin care, now we have four. So, you're right. So, when we are thinking about the resource allocation for the coming quarters, we may allocate more resources into the skin care growth. And the skin care growth might not be as dramatic as color cosmetics. However, we think the growth of skin care, especially the luxury centers of the skin care category is more sustainable and that this might influence the bottom line as well. So, for the second thing about the competitiveness of the color cosmetics market, so, if we look at the new monitored data -- so, last year, Yatsen as a company were -- was ranked as the No. 5 and then on, so, in 2019. In 2020, the company was ranked at No.4. But if you look at a growth rate of the 2020 over 2019 growth rate, at the -- based on the same database, Yatsen was growing at over 30%, while the No. 1, No. 2 was declining and that the No.3 was just growing at a single digit. So, if we look at the overall color cosmetics, we think we still have high-growth potential and that we will work to continuously expanding our brand in color cosmetics and we are -- we will continue to invest to grow our existing brands, including Perfect Diary until we become the No. 1 company in terms of value share in color cosmetic markets. So, your third question is about the increase in sales and marketing. So, in the first quarter this year, because we newly acquired a couple of the skin care brands, at the early integration stage, the investment in brand building and also cleaning the inventory for the distributors will be the two core things that we need to do. So, the investment for the -- our newly acquired brands, for example, we just announced the brand ambassador for Galenic in the first quarter. And then we believe the investment into strengthening the brand equity and then improving the brand awareness will be reflected in the growth in the coming quarters for our skin care brands.
