I will speak Chinese and Michael will translate in English. Even considering the regulation environment we have seen, we are still very confident in our overall annual growth in terms of revenues, especially we are confident that we are able to achieve that without relying on external staff acquisitions. Then, I will further elaborate on the reasons behind that. So first, in terms of the -- our in-school ecosystem, essentially it's not only a homework, it actually includes, class preparation, class delivery, homework assignments, as well as term assessments, which is comprehensive multiple scenarios interacting with the teachers, students and parents. Secondly, even in terms of homework, it can be completed by students in multiple types of devices, including PCs, pads, including mobile phones in home. Also in terms of completing homeworks at homes on different multiple devices, it was actually activities controlled by the parents and students themselves. So we don't see much impact on that. And also lastly, I think starting from last year's, we actually have been exploring probing domains where we are able to backup and duplicate the reach to parents and to various students our various social networks which further allow us to be less impacted in terms of the app itself. So therefore, those in terms of the near-term and the longer term of our integrate model, we are fairly confident because we believe if you look at things, three or five years or even longer cycle or longer horizons, the informatization and modernization of China's education system is irreversible. This is actually the only way to achieve or to improve education equality in China. So we are very confident as long as we can provide high values to the teachers, students and parents in class preparations, deliveries, homework, assessments, various learning and teaching scenarios. We are confident this is a model that has long prosperities. If some of you may be interested, you're encouraged to actually see the 14th five year plans, its interpretation and discussion about informatization of China's education over the next few years. We see very strong needs and the willingness to prepare this from China's government.
