Why can't Sichuan, Shaanxi and Gansu provinces hold a group to apply for the World Heritage?

First, first of all, Shu Dao is a proprietary cultural term, just like Jiangnan and Silk Road. Now the list of World Heritage should be China Shudao, and official website has a list. In history, besides Shaanxi and Gansu, there should be Chongqing, Yunnan, Tibet and Guizhou ~

Second, there are many places related to the history of this line, but not many actually survived, and most of them have disappeared or been destroyed. First of all, there must be valuable heritage sites. Sichuan's heritage sites are very rich and of high quality. Micang Road and some Jinniu Road in Guangyuan should remain relatively intact. Ancient Road Gubai Ancient Town Guguan Ancient Village Guzhai Ancient Bridge Ancient Temple Ancient Scenery Stone Carvings are quite spectacular. Moreover, Sichuan has been applying for the World Heritage for 10 years, and there are many natural and cultural relics, which are very weighty. All of them have been screened, and many related relics have been protected. Compared with Sichuan, there are very few related relics in other provinces, and related work has never been done before. The original site of the most valuable Shimen thirteen products in Shaanxi is also under the reservoir ~

It is not necessary to apply for historical heritage, but to see how many original and valuable things have been preserved now.
