I'm happy to hear that you will come to China. You have asked me about Chinese people's lifestyles and traditional Chinese customs. Here are some of my ideas.
First, when we Chinese people meet for the first time, we shake hands or nod heads. Second, we use chopsticks instead of knives and forks. Most people like to chat with others during the meal. Third, on birthdays we usually have a birthday cake and long noodles, and get presents. We should accept presents with both hands. Besides, the Spring Festival is the most important festival in China. People have a big family dinner together. Children get hongbao which means lucky money.
I am looking forward to seeing you soon. I hope you like China very much.
