Of course, sometimes students or parents will send small gifts to teachers, which is an affirmation of the value and contribution of teachers. This is a good thing. But the kind of parents who send things with a certain purpose is always daunting. For me, parents don't give gifts, and I don't expect teachers to accept gifts from parents.
I have been a teacher for so many years, and now I have some judgment on whether to accept gifts or not. Some students are from poor families, and I generally refuse to give them anything; It is also acceptable to give small gifts to those with good family circumstances. For example, a student sent me a bag of milk the other day, and I accepted it. If he gives me money, I won't accept it. When the results of the senior high school entrance examination came out, some students sent me flowers, so I accepted them.
