There is a field and depression on the plain, surrounded by highlands. Is feng shui good here?

Not necessarily. It depends on the terrain and the surrounding environment. A good feng shui should have: the former Suzaku, the later Xuanwu, the left Qinglong and the right White Tiger, the back front screen and the Wen Tai penholder, all of which are indispensable, as many people know. With the above, it is called gaining momentum, but the key is qi and holes (eyes). Good feng shui is very rare. Blessed by others, do more good deeds, and blessed by virtue is a blessing!
