If you are a woman, buy some fruit snacks. Generally speaking, we women don't bring anything when we meet our parents for the first time, but now times are different, and it's not appropriate to go empty-handed. We don't have such a thing as a gift, so the man's parents will accept it for you, and don't say anything without giving it to you. Because we don't have this local custom here, it is a custom to greet red envelopes in the south. We usually keep women for dinner, and girls usually help us cook after we finish eating.
