In which year is Zishan House suitable for building?

The noon position of Zi Shan (facing south) you mentioned is only one of the 24 mountains in Three Rivers Feng Shui; In fact, there is also a "Sanyuan Kong Xuan Feng Shui School", which divides 24 mountains into 60 melon mountains, and chooses the date according to the Sanyuan Jiuyun and the landlord's life (auspicious day and day shift).

All in all: it can be built in any year as long as the date is right! Don't you see that houses are being built and repaired everywhere, no matter what direction or year they are being repaired, most of them depend on the weather! )
