It may be that you are really not hungry or just don't want to eat. Everyone does. If it is your own constitution, it means that it is not suitable for drinking coffee. Drinking coffee is not good for you, and don't regard drinking coffee as a means to improve your living standard and realm and make yourself appear to be deliberately wanted by literature and art. If you really have this idea, you'd better die early. Will only be despised by others. Of course, most people believe that this is not an idea, but it is used to relieve the spirit and refresh the mind. But in China, not everyone is suitable for drinking coffee, and their physique is different.
