My uncle's son (my cousin died in Zhengzhou Hospital and they lived in Zhengzhou) died on April 7th. Is it appropriate for us to get married on May 1 day?

Defective immediate family members are not easy to get married in the near future, and non-immediate family members will relax. However, if your uncle or cousin used to be very close to your family, it is suggested to postpone it and tell everyone the reasons, so as to win the recognition of your family and improve your status in the family (of course, different families have different situations).

Choosing 5. 1 as the wedding day is not as meaningful as 6. 1.

Also depends on feng shui and the yellow calendar.
