Can I leave my memorial tablet at home after my uncle dies? He has no son.

In terms of blood relationship, you should be called "uncle". You are his nephew. He has no queen, and you are his queen. This is a big deal. Besides, from the perspective of Feng Shui, his soul is directly related to people of the same blood. You worship him, and he will bless you. On the contrary, it will be bad for you. From the point of view of doing good, this is the virtue of doing good.
