Linda, this is Su Peng. I will take these questions. And indeed, recently COVID issues in some cities in China actually have some impact on our business. Yes, we also come out with some contingency plan and try to mitigate about the impact. And we will divide it into that -- into 2 parts because with the different impact on this business. And as for the Learner Services segment, that's well our major revenue generated from. And I think our process of our services is primarily delivered via the Internet. So we don't need that really the physical contact with our customers. Most of our services have been offering over the online channels instead of the offline learning centers. So what we think about we have very limited -- a very, very limited impact on the online learning services business. And so that's the first part. And secondly, as for the -- they do have some impact on our Smart Devices segment. And it's because of the smart devices, whatever they purchase is online or they purchase on the retail store, we have to deliver our products to our customer, that will be related to the logistics transportation issues. So we think about right now, indeed, that part, we have some challenging things regarding logistics and transportation for our products to our customers. But we think about all of that will be the short-term impact. In the long run, we don't think -- by now, we don't think about -- there's any impact on the demand from our customers regarding on the services provided by our smart devices from Youdao because we see a very strong momentum and the demand from customers in the last several quarters regarding new pen. You can see about the growth rate and the growth trend of our Smart Devices business in the last several quarters. So, we think about -- so I think in the long run, that will go back to the normal. And indeed, we do -- by now, we are -- definitely, we are doing something to mitigate about the impact short term. And for example, we are setting up the new warehouse in Tianjin, Chengdu, Wuhan and other area in Mainland, China and to delivering these smart devices directly to the region distributors. So we think about that's what we did, and we hope we can just mitigate about the impact short term, and we expect we can see the -- we expect to see the business go back to normal right after the impact the COVID has been caused. I think that will -- we expect renewals in the middle of the Q2, and we expect to share more information after we finish out the Q2 season. Thank you.
