Thank you so much for the questions. Last quarter, our utilization rates have been slightly increased, around 1% and because in our classes, the – since fulfillment is always high, and retention rate is also very healthy, so we believe maybe in the long run, we still have maybe low single digit percentage of potential to increase in these metrics. But that's it, don’t be too optimistic about that, because we are already quite high. And secondly, about expansions, this year, you probably can see in Q3, we entered 11 new cities, so dual teacher models. So let me clarify, since around one or two some 18 months ago, we have decided we don't expand our offline model to new cities. Most of the places we enter actually through dual teacher models, last year, we entered around 12 cities, and now, this year, by the end of today, it’s 11 cities. And at the same time, we also see huge, sorry, we also see very healthy growth form the online segment respective with tripe digit. So we need to, as a company, we need to balance, we have the high growth drivers in online, we have a new model called dual teacher models and we have the offline, which is our traditional models, we need to balance all of that. If we can drive the growth through online, which is more kind of -- which is better, then we can drive the growth simply from offline. So, looking forward, we will continue to balance our three drivers and making sure we can leverage the advantages of different drivers to try to penetrate more cities in a more healthy way. But I can’t figure out today to say, we will expand faster or slower of next year offline network. So we probably will continue to give you guys numbers quarter over quarter and we will continue to follow all of the government policies and regulations to make sure the new living standards we enter is compliant with the government requirements. So, we definitely will, just stay tuned, we definitely will give you guys numbers quarter over quarter.
