Culture-greeting

In daily life, acquaintances usually greet each other in informal way. Here are two examples:

audio - 你吃了吗(Nǐ chī le ma)? (Have you eaten yet?) — When it is around the meal time.

audio - 你去哪儿(Nǐ qù nǎr)? (Where are you going?) — When we see each other on the way.

These ways of greeting are warm-hearted because all of them are about life trifles. We just answer these questions according to real situations, but we don’t have to give details.
