C53 Uncle Wang's Conundrum

I was confused. Originally, I wanted to ask him what he understood and he said that we would first head to the ancestral hall. I was curious as to what he had been doing in the ancestral hall.

This time, Grandpa took me to the back door, but we, the Ji Clan's ancestral hall, usually don't open unless there is a special ceremony, so opening the ancestral hall is always a big matter for us
