In general, you should go to the woman's house first, and then to the man's house, because most people think this is a respect for the woman and her family. But with the constant change of modern people's thinking, there is little controversy about who to go to first. In most cases, the two families will make an appointment and then go to a restaurant to eat and chat.
According to the traditional wedding custom in China, the man must go to the woman's house first, because people in China pay special attention to this ceremony.
