The quality of a city's geomantic omen does not depend on the natural geomantic omen in a narrow area, but on the basis of the overall natural geomantic omen, which dominates the city's political geomantic omen, economic geomantic omen and human geomantic omen. For example, in the 1980s, there was a township government across the river. Due to the existence of government agencies, there is only one commercial outlet, and there are more than a dozen shops on the other side of the river that are the largest in the local area, forming a lively small market. Due to various reasons, township government agencies moved to other places, where there was a "sudden cooling" immediately. In less than three months, more than a dozen of the biggest stores can't keep going, and the three small shops left are just a stall, without the prosperity of the past. A small township government does not have an independent financial function foundation, and its influence ability can bring geomantic effect, not to mention a larger government agency with independent decision-making function and financial function, and its influence geomantic effect can be imagined to be even greater. It can also be inferred from this example that the geomantic omen of a city is determined by political geomantic omen, economic geomantic omen and humanistic geomantic omen formed on the basis of natural geomantic omen. The close combination of political geography geomantic omen, economic geography geomantic omen, human geography geomantic omen and natural geography geomantic omen is a complete geomantic omen.
