In our daily life, it is common for you to meet a familiar person, but some greetings will offend people. Although you think it is funny, others are unhappy.

"Sister, long time no see, the food is good, and you have gained weight again." This sentence is very destructive to women, especially easy to offend them.

When we greet others, we must pay attention to the collocation of words and don't talk nonsense, which is easy to offend people.
