Why does Jiuhuashan's income belong to Hefei?

The reason is that Chizhou where Jiuhuashan is located is a unit under the jurisdiction of Hefei. The tourism income and related economic benefits of Jiuhuashan Mountain are included in Hefei's fiscal revenue to some extent through taxation, profit sharing or other means. This is because Hefei, as a superior administrative unit, bears the responsibility of providing infrastructure, tourism promotion and management, so it enjoys the benefits of subordinate units such as Jiuhuashan to a certain extent.
