Because of the poor sanitary system, ancient toilets were smelly, which had a bad influence on people's physiology and psychology. However, ancient geomantic classics also show that toilets have the theory of gathering wealth, so there is no absolute good or bad.
The modern sanitary drainage system is very advanced, which completely avoids the feeling of dirty gas welcoming people (unless the cleaners are lazy ...), so there is absolutely no need to overemphasize the dirty gas in the toilet.
Modern and even ancient Feng Shui is handled in the form of "lattice", and there is no absolutely the same form of Feng Shui, but Feng Shui is more vital (since ancient times), so modern Feng Shui pays more attention to flexible learning and application-at least in ancient times, it was not expected that there would be 70-80-story high-rise Feng Shui (hehe).
