I'm just a high school student and I have to go to school. I have 1000 yuan in my hand. I'm thinking of buying an mp4 or saving it or doing something else. I hope you can give me some money.

I suggest saving it first. First of all, you are not sure where the other party will spend the money. That is to say, the MP4 you are considering buying now is not what you need urgently. MP4 is not your necessity, and digital products like P4 can be updated quickly. Considering that you are a high school student, using MP4 may take up your study time. High school students should try their best to spend time on their studies (moderate activities and rest are essential), and these things can be bought later. There may be something you really want in your later years, or when you need money badly, it is not too late to use it at this time. There is also the need to learn how to manage money.
