But looking at your question, I don't think it has anything to do with Feng Shui (I don't believe in Feng Shui). It is entirely because the housing conditions are too bad, and the surrounding environment is dirty, chaotic and poor. It is strange not to get sick. I don't believe in evil spirits in this house. Too heavy is just too heavy moisture. In addition, I don't see the sun very much, and tenants don't pay attention to hygiene, which is easy to breed bacteria. It's only a matter of time before I get sick. There is nothing to say about the excessive formaldehyde in the back house, and there is a decoration problem. I don't know the details of the cracking of vases and fish tanks, so I don't judge, but it is said that suffocation can break them ~ who believes it?
Whether to stay in Hangzhou or go to Yiwu depends entirely on your career plan, but wherever you go, you should be cautious in renting a house, with good light, at least sunshine, and clean surroundings, especially in public places.
If you rent the same house after moving to Yiwu, you will get sick and it will be useless to move to Tianya.
