Is the Kuitunhe Grand Canyon the Dushanzi Grand Canyon?

This question seems a bit complicated. The canyon is located in Dushanzi, and Dushanzi has developed it into a formal tourist attraction. The name of the scenic spot is naturally called "Dushanzi Grand Canyon". The river in the canyon is the Kuitun River. Before the Grand Canyon was developed into a scenic spot, the locals naturally called the canyon "Kuitun River Grand Canyon". In other words, "Kuitun River Grand Canyon" is a naturally formed place name, while "Dushanzi Grand Canyon" is an artificial place name. Theoretically, "Dushanzi Grand Canyon" can only refer to scenic spots, at most extending to the part of the canyon within the administrative division of Dushanzi, while "Kuitun River Grand Canyon" can refer to the entire canyon area along the Kuitun River. In this sense, It can also be considered that "Dushanzi Grand Canyon" is a part of "Kuitun River Grand Canyon". <br/>However, these two names also involve local interests. Dushanzi is adjacent to Kuitun City, and Kuitun City deliberately uses the name "Kuitun River Grand Canyon" to promote it, so that foreign tourists who don't know the truth will easily mistakenly think that the Grand Canyon is located in Kuitun City, which will increase tourism-related income for Kuitun City (there are indeed many Tourists use Kuitun instead of Dushanzi as their foothold, bringing income from catering and accommodation to Kuitun). In order to prevent Kuitun City from taking its own tourism resources, Dushanzi deliberately avoided the term "Kuitun River Grand Canyon" (although Kuitun River and Kuitun City are not the same thing).
