The reasons for the location change of China's ancient capital.

Nothing more than political reasons, economic reasons, geographical reasons, war reasons and feng shui reasons.

The political reason is to consolidate the imperial power and ease the contradictions among all parties;

The economic reason is that the development of the old city is limited, which limits the economic development;

The geographical reason is that the geographical location of the old city is no longer suitable;

The reason of the war is that the old city was destroyed by the war or vulnerable to the threat of war (especially when the military strength is weak);

The reasons for geomantic omen are all kinds of ups and downs, which are attributed to bad or changed geomantic omen, and the destruction of environmental ecology is also classified here.
