Yes. I'll address the first part of the question about -- around engagement and monetization, and then I'll let Shirley take the margin question. It's -- I think we're actually very pleased. I mean this quarter, as we mentioned, we announced quite a few product enhancements that are very much focused on increasing user engagement. You saw TME Live, you saw our Putong Community, the increasing video enrichments across pretty much all of our apps in QQ Music, Kugou Music and WeSing. In WeSing 7.0, you saw more interactive features around community, increasing adoption of online singing rooms, promoting more, publishing activities by our KOLs as well as our ordinary users. I think all of these are very much focused on building a long-term, sustainable and healthy platform, which -- from which, obviously, there will be a plan to monetize. We are seeing very good metrics. So for example, for Putong Community that you mentioned, the DAU penetration is increasing, and the total number of songs reviewed that are coming on the back of the Putong Community exceeded over 1 million, right, in a very short span of time. In terms of the video enrichment within, for example, QQ Music or Kugou Music, we're seeing increasing video content, DAU consumption penetration, right, increasing sequentially. I quoted some metrics around online karaoke in terms of the video publishing activities, which are seeing very exciting growth. So I think all of these are very healthy for the overall sustainability and long-term growth of the platform. And in terms of monetization, you're actually right. We do see advertising as an other -- third major revenue source behind subscription and live streaming. In fact, we have said in the last quarter that we are actively hiring to increase our team as well as increase our advertising product and technology behind that. You will see us do more as we proceed into the second half, and advertising revenue will ramp up substantially next year.
