Okay, sure. Hi, Eddie, it's Tony, let me address both of your questions. With respect to the music paying users, I want to reiterate that 27% year-over-year growth for our music paying user is a very healthy pace. And with the mobile data cost declining, the paying user conversion driven by pay for download is facing some headwinds, while the paying users are driven by pay-for-stream is actually enjoying a lot of headwind as Kar Shun mentioned in his speech. And however, because the pay for stream user base is relatively small, because we only started implementing the pay-for-stream model in Q1, it will require some time for that to ramp up. So this is a particular quarter where you see that impact between the netting of the headwinds and the tailwinds, playing out the most. Over time into the next quarter and beyond, we expect the paying user growth to improve. And now in addition to growing the paying users, we've also made a lot of progress on improving the subscriber retention rate over the last several quarters as Kar Shun mentioned. And that's driven by our continued investment in enriching the content offering, as well as some of our promotional campaigns on auto renewal program. So our focus is not only on the quantity of paying users, but also on the quality of the paying users. On the pay-for-stream development specifically, we have made - we started implementation of pay-for-stream on transition model with a small selection of content in Q1. While the amount of content being put behind the pay-for-stream paywall accounts for only a very small percentage of our total. This is just the beginning and we'll continue to gradually add more content over time. The current focus is on making sure the user experience remain good despite that transition, and it will take some time for us to promote a broader user adoption. We are seeing encouraging results so far, which gives us the confidence that this is the right strategy that can generate significant value for the company over the long-term. So that's on the music side. And then on the social entertainment side, I also want to stress that while the MAU growth is seem slow, the overall social entertainment grew at a very healthy pace at 45% year-over-year. And we recognize that MAU growth has slowed. But I think one also has to recognize that our MAU base is already very sizable. Now, historically, our focus was more on the core karaoke users with relatively higher user frequency and as a result we have been very successful in mapping a large group of such core karaoke users. And hence we are reaching a high level of penetration within that core user group now. But we already have a well-defined plan to address this and to propel the user growth going forward. We will execute a number of initiatives focused on expanding the user coverage beyond the traditional user group. Some of the examples I've already mentioned earlier on the call, for example, we will continue to leverage the WeChat Mini program that offer a more simplified singing feature it capture more users within a larger social networks within WeChat. We continue to expand target users through the lite version of our app with more simplified product experience tackling fewer singing features, we will lower the karaoke usage barrier by allowing user to sing only part of the song such as the chorus, instead of the full song, and combine that with the one click sound correction feature that we mentioned in the last quarter will both help reduce the usage barrier. And finally we'll continue to invest in innovative product features to continue to deliver a fun and engaging user experience, such as the multi-mic singing room we mentioned in last quarter that is starting to bear fruit, and also the Grab the Mic, new feature that we launched in this quarter. So combining all of that being said we're very confident our user growth plans will start to drive better user growth in Q2.
