How to solve the problem that it is not suitable for mourning but must be mourned?

The answer is: you can't attend the funeral. Looks like you can't tell me anything. You have to attend again, which means that the deceased is very important to you. I think, just explain the reason, don't be too hard on yourself. Because you can't hurt yourself because of this.

If it really doesn't work, then you have to run with the bull! No big deal. Correct attitude, solemnly bow to the deceased three times and express condolences. Finally, comfort the family of the deceased, show concern, and then it will be all right.

When you are free, say hello to colleagues and friends who come to pay New Year greetings, greet each other, pay attention to all aspects, wear masks and pay attention to safety, and everything will be fine.
