Thank you, Brian. In Q1, we faced a few short-term challenges due to the pandemic's impact on our primary businesses that is learning services and devices. However, strong advertising results partially offset that decline. And both learning services and devices rapidly recovered in the second half of Q1. So we expect that the negative impact of Q1 to be a one-time event. Our confidence for the full year 2023 comes from several reasons. First, for learning services, we actually see strong demand. And we have a strong and growing product lineup. As we mentioned earlier, learning services in gross billings, excluding adult courses, grew by over 40% in Q1. So that's actually quite strong growth. The growth is driven by both strong demand and the rollout of new and updated digital content services, including updates to Youdao Literature digital content for high school and also Youdao Fun Reading, as we mentioned, and we have more new learning services in the pipeline for later this year. So we are confident about learning services growth. Secondly, for devices, we are also seeing good recovery. Dictionary pen activations, that's for new devices. In March, we're up 20% year-over-year. So we plan to release new devices in Q3. So we believe -- so updates to existing devices through software and also new devices this year will also drive growth, given the high market share in dictionary pen market and also the other products that we have. Thirdly, for ads, back in Q4, we reported accelerated growth from ads at 58%, almost 60% year-over-year. In Q1 that was even higher at 80%. So we believe we are in an advertisement of growth cycle due to two factors. One is our significant algorithm updates to the platform in Q4 proves to be very effective, allowing us to attract more customers and more budget. Now also, in the current macro environment, businesses are actually leaning to performance ads, which is our main form of advertisement service that we render to our customers. Performance ads are what businesses are actually relying on to accelerate their recovery. So we expect the advertisement's growth cycle to continue. So although we had a kind of a hiccup in Q1, but as I've just shown, we think that the overall business is in a healthy state. We are executing towards our goals this year, and so we are quite confident about our development for the full year 2023. I hope that answers your questions. Thank you.
