How can there be a pond in front of the ancestral temple ~ ~ ~

This is what traditional architecture in China requires: hiding wind and taking water. It can also be interpreted as: looking ahead and looking back, or facing the mountain and facing the water. In other words, in temples, ancestral halls and other buildings, we should try to choose places with water behind and in front of the door. If the door is far from the water source, you should dig pools, canals and ponds to make up for it.
