How to test your feng shui?

If you don't know Feng Shui, you don't want to pay someone to look at it for you. Please bring a dog or a baby under three years old to your home. If the dog walks around and wags its tail when it gets home, or you put the baby on the ground to see if it can crawl and play by itself, it means this place is not bad. If the dog stops or barks in one place, or the baby cries. Explain that it is not appropriate to stay here for a long time, otherwise everything will go wrong.
