Okay, let me take the question about the gross profit margin. Actually, if you look at the revenue sharing costs that we already disclosed, in Q4, that number is around 78% of the revenues. So that means that we don't pay too much to those kind of users. For the individual business segments like games, actually, for exclusive games, the gross profit margin is quite stable, like 55% for exclusive game license. Therefore, the whole operation model, the -- we don't share any profit to third parties. So that means that the GP margin will be around 100%. And for the live broadcasting, currently, the gross profit is not that high, but actually, if you count the -- our subscription membership revenues, the overall margin is still reasonable. So we will not like to calculate gross profit margin in like just to look at 1 quarter or 2 quarter numbers. We will keep investing our Comic business so that we will incur more content cost for our comic, and we will also invest in different areas like virtual idol, Luo Tianyi, that will help us to grow our community. So in the short term, like 1 or 2 quarters, the gross profit margin may be -- have some fluctuations. You already saw that in Q3 and Q4. Also, there might be some pressure in Q1. But in the long run, I think the investment for today is to have their value to help us to achieve more stabilized sales mix. At that time, we foresee that when normalized, our gross profit margin, where we have 50% revenue from games and 30% from advertising and 20% from VAS, that means the gross profit margin will be around 40%. That's our projection.
