Actually, I don't think you need to be so nervous when you come up. It will be difficult at first. After all, you haven't touched it, and you don't understand it at all. But I think everything is, you have to understand it yourself to know. Just like three months ago, I have no experience. When I first went to Zhu Cheng to give a speech, I was scared, but when I got to know it, I would find nothing. Take your time. If you are afraid at first, it will be embarrassing.
