A fortune-telling red cloth thrown into the water

According to the book "Return All Laws to the Ancestor", you are talking about Wujie Town, because it was designed according to the owner's life at that time, with the aim of housing in the town. Because the owner changed his new house, there was no need to use it again, so he didn't take it away. This thing is not good for you, because your age is different from that of the previous owner. You just have to throw it at the rapids and you can be sure.
