Cultural tips

Greetings:
There are not many differences in greetings between the Chinese people and Westerners. For example, when one meets and leaves someone, one says Hello and Goodbye, respectively, and so on. But in daily lives between people who are familiar with each other, their greetings are generally based on their situation and thoughts at that moment. For example, when two people meet, one will ask the other casually some questions like "Where you are going?" "Are you going to work?" "Did you eat?". Upon hearing these questions, a lot of westerners won't understand. 

Because most westerners would consider these questions as private matters, which shouldn't be asked so casually. So, when they meet, they often greet each other by simply saying: Hi / Hello! Good morning! How are you? Or talking about the weather, such as the weather is beautiful, isn't it?
