Sure, so regarding the different sales channels, yes, so right now, over 50% of our devices sales are through online channels, yes. So the -- of course, the major e-commerce services are the key online channels. And also we have the live channels, the live video channels for sales of these devices also online. And the offline channels are also very important to us because we have been working with these partners for a long time. And through the several thousand, we have several thousand sales endpoints across the country, these are actually very important for kind of mid-income areas, not the Tier 1 cities, but the mid-income areas, mid-income cities. A lot of customers there, they like to buy pirated devices from the offline shops. And the Q2, the impact from COVID, it's actually several factors. Yes, let me explain that a little bit. So one is actually the delivery process. And the impact kind of is -- the key reason is that when people go online, they want to order a device. When they see that the device kind of takes several weeks or even sometimes even longer to arrive, it impacts their willingness to place the order. So that impacts our overall sales process and efficiency. So that's 1 of the key reasons. Of course, in kind of -- in Shanghai where people, they don't have -- the delivery cannot happen at all. Of course, there's basically no sales. But for other areas, there's still impact because of the logistic kind of difficulties. And the other impact is for storage and -- for the storage of the devices that we have some warehouses that's within the impacted area. So that's also another factor. And looking ahead, as I said, I think the local governments are getting increasingly better at handling the COVID events without actually incurring a lot of logistics troubles. So we see that as a fact that will help down the line. And also, we have also -- we have also kind of rearranged our warehouses so that it's more diversified in terms of locations. So we think that should help too. So overall, we are pretty -- we see promising trends for the device sales in the coming quarters. And the new Dictionary Pen X5 is -- we think it's a great product. So yes, check out the video on our IR website, and I think you will like it. And of course, we are looking at from -- to look at this from a very long perspective. So we think our teams have a lot of experience in designing good devices. So the learning tablets, learning pads are a very important category for us. So we will look at this category very carefully, and we will have new devices down the line. So yes, we will keep you posted.
