Is there a website or app for tourist route planning in China?

For domestic route planning, for example, if you want to plan a four-day trip from Chongqing to Chengdu, it is suggested to use "cutting travel" directly. I found that I don't need to find any strategies at all, just generate the itinerary directly. Hotel restaurants also recommend that WeChat pay attention to "cutting travel", and the official WeChat account can be used directly. In addition, I see that there is also a practical function "tourist map". After the opening, all the scenic spots are clearly marked on the city map, and there is an introduction when you click in.
