What color tiles are stuck on the gate? Feng shui taboo.

This has nothing to do with feng shui. You can post any color you like, but it's best not to post the red one. Generally, the red gate is only used in temples, and nothing else matters. It's best not to be too casual. In fact, there are not many things related to feng shui in life. Not everything is related to Feng Shui, so don't tie everything to Feng Shui.
