Okay, Mark. Yes. We’ve beaten the margin guidance a lot. Our non-GAAP operating margin rose by 720 basis points in this quarter. I think it's because of the following reasons. Number one is, I think the continued margin expansion is mainly driven by the better utilization of the facilities. Typically, our-top line growth is over 30% year-over-year in RMB terms, but the expansion in last trailing 12 months is just 25%. And also number two is, we’ve built a standardized and modularized and systemized operating process. So, you see the results. We achieved outstanding improvements in the operational efficiencies, and we get a lot of leverage on the selling, marketing, and G&A expenses. And finally, we're seeing the revenue acceleration. Typically, we're taking market share from the small player in the market. So, the revenues are very good. And I think those three reasons get us the better results of the margin expansion. As I mentioned in the prepared remarks, in the rest of the year, even in the Q3 and Q2 in fiscal year running, I think we’ve still got more leverage going forward. So, we believe, we will have the margin expansion in the rest of this fiscal year, and even for fiscal year 2021 I think our margin will get the expansion as this year, okay? And the revenue breakdown, yes, in the Q3 revenue guidance, I think the K-12, business will grow by 40% in RMB terms. What I’m saying is in RMB terms year-over-year growth 40%, and overseas test prep I think to the low-single-digit growth. And the domestic test prep, it will be down by let’s say 3% to 4%. And the overseas consulting business, the growth will be over 20%. So, this is the breakdown of the Q3 guidance.
