Feng Shui is an ancient traditional culture in China, involving many details and skills. According to the information provided by you, "Yin Zhai Li Hai Shan has been divided into two directions and branches (Ding Hai Fen Jin)" is a language describing the relationship between housing pattern and orientation, including concepts such as vertical, sitting orientation and five elements.
It should be noted that the layout of building foundation geomantic omen should be combined with the actual situation and consider the comprehensive influence of many factors, rather than simply judging whether it is appropriate according to a formula or law. Therefore, it is impossible to make a concrete evaluation of the feng shui of this secluded house by simply describing it.
If you need to evaluate and adjust the geomantic omen of Yin House, it is recommended to consult professional geomantic omen or geomantic omen masters, who will provide you with more effective suggestions and schemes according to more detailed conditions and the results of field visits.
