The core of Yi-ology is simplicity, changeability and difficulty. Everything in the universe is changing. Different geographical environment, different climate and different customs will directly affect the layout of Feng Shui. Since the core of Zhouyi is change, we cannot rest on our laurels. China's geomantic omen should be taken abroad. It should be based on the principle of easy learning and should be changed accordingly. It is absolutely not applicable to copy mechanically.
For example. Let's say our country, Guangdong is rainy and humid, and even clothes are not dried in the rainy season. If the south is ventilated, all the electrical appliances and furniture in the house are wet and the north is dry. If a certain point in the north is difficult to cover Guangdong in the layout of geomantic omen, this room can't live in the rainy season.
