1, green hat, as we all know, can't be given away casually. The green hat means "wearing a green hat", which means that someone in the family is cheating. It is very bad to give the green hat away. Unless it is, you don't like that your best friend/brother is "green" and you are embarrassed to say it directly, then you can send a green hat to Ta for a hint.
Straw hats and white hats can't be given away casually. In folk customs, the elders in the family died, and as descendants, they need to wear white mourning hats and linen. And when you give someone a white hat, you will have a feeling of cursing other people's families.
There is also a folk saying that the hat is on the top of your head. Sending a hat will make people feel that you want to press someone's head, so it is not recommended to send a hat.
Giving gifts is taboo.
