Dongyang custom: the gift money can be refunded. How much to keep and how much to return is up to the woman. In fact, it should be privately agreed by the man and the woman through the matchmaker in advance.

Worship your uncle means that the groom worships the woman's brother or younger brother. The red envelope is given by the woman (it can be counted in the gift, depending on the woman's dignity), and the groom receives the red envelope.
