When a Chinese meet someone for the first time, they normally start from” Hello, I am called, please….
When Chinese meet someone who see each other every day, for example, classmates or colleges. They normally say” morning” or “good morning”, which is similar to English convention. If you are very close to that person, normally you will ask something more “Have you had brekkie?” to show that you care about that person.
When Chinese happen to meet someone who haven’t seen each other for a long time, they normally say” long time no see, how are you going recently?” We should hang out some time.
The answer would be “good”, “not bad”, or “so so”.
But “How are you” would never be used in Chinese daily greetings.
