I am also the beneficiary of Zhong Qian. My clinical teaching assistant's lectures are the key points, and they are all test sites. This is very important. I used to read books by myself and forgot to read them. I am so grateful to Zhong Qian. The sooner I take it out, the better. I heard that drivers' licenses, for example, will become more and more strict and difficult to take, so colleagues, we are pressed for time, and the sooner the better.
