Is it appropriate to send half a flower?

When considering whether to send half a flower, you need to combine the specific situation and the relationship between the other party and you. If your relationship is very close and the other person is your elder, then in this case, it is more appropriate to send half a flower. This shows that you have filial piety, and the other party will generally understand and feel gratified. However, if your relationship is not close enough, or if the other person is a peer or junior, it may not be appropriate to send half a flower, which may make the other person feel that you are not generous enough or look down on them.

In short, when choosing gifts, you should consider each other's feelings and the relationship between you, and try to avoid causing unnecessary misunderstanding or offense.
