What should I say if someone doesn’t accept my gift?

Euphemistic refusal method:

Euphemistically refusing for some reason does not directly indicate that one does not want the gift, but makes the other party feel that there is indeed a reason not to accept the gift, so they give up. Keep giving gifts.

2. Later return method;

Accept the gift at the time, but return the gift given to you by others at the appropriate time and place afterwards

3. Direct refusal method:

When someone else expresses that they want to give you a gift, tell them directly that you do not want to accept the gift, so that they will stop giving gifts.
