Thank you, Alex, for your questions. This is Jiandong. I'm going to answer your two questions. The first one, sales and marketing expenses as a percentage of revenue dropped in quarter 4 2018. If you look at the sales and marketing expenses in absolute dollar amount, which actually increased roughly about 13% compared to the same period last year. If you compare the same period, the revenue growth, actually our revenue growth, at a much higher degree in the fourth quarter of 2018 versus the 2017, which is roughly 27 - more than 27%. So which explains partly why the total selling and marketing expenses as a percentage of revenue in Q4 dropped. Meanwhile, as we stated in our Q3, we increased our investment in selling and marketing expenses starting from Q3 2017. We started testing a few new online channels, and we collected more data in Q3, which give us a better understanding of the effectiveness of different channels. And we can do a much more effective targeted marketing by using the channels in a more effective way, which actually increased the return in our investment in selling and marketing expenses. And the other factor contributing to a drop in selling and marketing expenses as a percentage of revenue is because we actually maintain a pretty steady selling team, sales team in quarter four, which actually increased our conversion rate. So in short, I will summarize in 3 points. One, because the investment in selling and marketing expenses in Q4 2018 actually drives a much higher growth degree for our Q4 revenue; and second, because our investment in online marketing channels are more effective, which generates better quality leads, and that increase the return on our investment in selling and marketing expenses. Meanwhile, we maintain quite a stable sales team, which increased our total conversion rate. So in short, that explains the drop of the selling and marketing expenses as a percentage of revenue. However, given the overall understanding of the market computation, we still feel we need to further - in order to further maintain our growth momentum and further increase our total student enrollment, we need to further increase our investment in selling and marketing expenses. So we'll kind of maintain our investment in selling and marketing expenses and keep it as a steady percentage of our revenue in 2019. Sorry to be wordy. So for question 2, for our Q4 - Q1 guidance 2019, I would say that in the second quarter of 2018, we were hit by the market pressure. And our total enrollment of new students in the second quarter of 2018 as well as in Q3 2018 was somewhat increased, but not at an expected degree, when it's all those enrollment study to recognize revenue in Q4, which lead to a lower revenue recognition in Q1. So that somewhat explains why our Q1 revenue increase is a bit lower. Did I answer your question on the second one?
