I'm only vaguely familiar with the Chinese system. Regardless, there is a substantial relationship between subsurface geology and surface-expressed biology, topography, even in some cases microclimate and audio. This was known to traditional societies but is becoming lost in our time as we disconnect from the biomes we are destroying and concrete-pouring. Anyone who has substantial knowledge of native plants can and will verify the same. I believe you could place many pre-modern humans in a random location within their domain and, blindfolded, after a minute they could likely tell you which plants and animals were nearby, what they thrived on, the nearby soil types and hydrology, the time of day, and the season.
