My nephew asked my uncle to do something. What do you mean two bottles of wine were returned?

According to your description, your nephew brought two bottles of wine when he asked for something, and they were returned. There are several possible explanations for this situation:

1. Gifts are not in compliance with regulations: on some occasions, especially when government agencies are working, there may be regulations prohibiting accepting gifts. If this is your nephew's case, then returning wine may be because accepting gifts violates relevant regulations.

2. Illegal acts: According to the laws of China, bribery and other acts are serious illegal acts. If your nephew tries to get special treatment or pay bribes by giving gifts, the relevant departments may refuse to accept the wine and investigate it.

3. Special requirements: Another possibility is that the relevant departments have special regulations on receiving gifts. For example, they may only accept gifts of certain specifications or brands, and the wine provided by your nephew may not meet these requirements, so it was returned.

The best way is to ask your nephew or relevant departments to find out the specific reasons for returning wine. However, please remember that under any circumstances, participating in bribery or bribery activities is immoral and illegal and should be strictly avoided.
