Yes, okay. For the first question, regarding the new student enrollment, yes, the new student enrollment for this quarter declined slightly compared to last quarter. And -- well, the main reason for that as our CEO, Tongbo, mentioned, we started to do this introduction seminar and free trial classes during the second quarter and especially we are expanding the scope in the third quarter. For those students who take part in free trial classes and introduction seminars, they are not defined as a new student enrollment if they are not contributing to our current quarter revenue. So that's actually the major reason for the company, why there is a decline in terms of new student enrollment. But we are very confident in the long term, once those students -- once they take the free seminar -- introduction seminar and the free trial classes, they will have a much higher conversion rate and a much lower refund rate. And based on, right now, the limited data we have, we have noticed this trend. So that's the answer for your first question. And for the second question, in terms of our ASP, our ASP for Q3 increased significantly comparatively as in Q2, and that's mainly due to the product mix. Like Tongbo mentioned, we introduced AI-powered class and some other value-added services class in Q3, and the students who apply for those classes are actually willing to pay a higher ASP compared to the product without those value-added services. So that's the major reason for the company -- our ASP is much higher compared to last quarter because of the product mix, not because we increased our product price. And for your last question, regarding the marketing effectiveness ratio, the marketing effectiveness ratio for this quarter is a little bit higher compared to Q2. That's mainly due to right now, the traffic cost in China is more and more expensive, but the company is favoring all kinds of ways and channels, and we think in a few quarters we will see very positive results. Well, actually one thing I want to add here is, the higher sales and marketing expenses as a percentage of our net revenue actually declined in Q3 compared to Q2, and, although the marketing spending is more expensive, that's because in terms of employee -- sales personnel productivity, it actually improved a lot compared to last quarter. So that's why the total sales and marketing expenses, as a percentage of net revenue, declined compared to last quarter.
