Maybe I'll just translate the first two responses while Mr. Chen will respond to the third question. So in terms of the online product launch event, it was actually very successful, able to reach over 2 million views since last week. So a very high viewership, which is a signal of very high interest in the direction of not only Viomi but also in terms of Viomi's positioning in the upcoming kind of 5G and IoT era, which has been a very hot topic in the industry. I think the news reports and feedback that we received have been very plentiful and overall quite positive and has really kind of increased the interest in Viomi and Viomi's direction among industry watchers, not only in the sense of smart appliances, but also in terms of the broader 5G and IoT industry. So I think some key points with regards to the event. The interactive smart screen TV that we launched, I think this will, as mentioned, be very central to our IoT @ Home experience. It essentially completes the IoT @ Home scenario in terms of our product coverage, being a focal point of the living room. So a screen in your living room, being able to engage in cross-operability and cross-screen experience across scenarios and environments in your home. Secondly is the Home SaaS cloud services that we announced. So this concept, it really kind of brings the fact that we're not only offering products, but really pushing this holistic IoT concept, right? So Viomi's 5G + IoT strategy places a marker for Viomi's future strategy, direction and positioning as not just a products provider but in terms of a holistic kind of IoT experience play. The second question on 5G. So 5G, we do expect this to have quite a revolutionary impact on the kind of home appliances industry or the IoT @ Home industry, quite similar to what's currently underway in the mobile phone industry. So I think there's several kind of easy-to-understand concepts of 5G so -- is that it will directly upgrade routers and current WiFi connectivity, resulting in faster connections, being able to connect more products at the same time and offering automatic connections, right, so very easy to use and seamless connections for the end consumer. So the overall 5G + IoT ecosystem, we envisage to be more flexible, being able to offer more high-quality content and, I think in the end, will offer a better experience and better value proposition for consumers. And what is this value proposition? I think we want consumers to really get into this next-generation idea of the high-tech home. So what will it be like? So I think over the next period, it will be important to educate consumers on our vision for what the future home should be and how we can help them achieve this to essentially upgrade their home living experience. So Mr. Chen will now provide the answer for the third question on interoperability.
