If you want to have a good impression, start with the impression of modesty, naturalness, elegance and a little shyness, and then go to the etiquette section. From good morning and the first meeting, please pay more attention to what kind of tea you like. Please make yourself at home. Can I eat? Are you used to the climate, food and water here? How do you like it here? I like Japanese topics very much. Japanese people pay special attention to details, such as sneezing and dozing off. You must turn around and cover your mouth. You should always pay attention to whether there is rice residue on your mouth and stretching. You should pay more attention to similar behaviors, because these will greatly reduce your score. Many of them don't need language impression, do they? Keep your words and deeds in mind. I believe it will leave a good impression on him. Come on!
