However, this is not important. There are few square buildings now, and the theory of architectural geomantic omen is inherited by later generations, mainly from the theory of ancestors looking at bungalows. Some theories (such as missing corners) seem far-fetched and rarely come true in practice, because the building is a whole, and what you lack has been made up by other residents. But it is better to solve some:
1, the dragon and snake zodiac (Tatsumi); 2, put Taishan stone to dissolve (there is no need to write, the size is conducive to decoration); 3, the town symbol (it is easy to be superstitious or free).
By the way, although some architectural geomantic theories are far-fetched, many of them have been proved to be correct by practice.
