The waterwheel is a landmark building in the ancient city of Lijiang. Almost all the tour groups will gather here. Even some regiments would not go into the ancient city, just take a picture here, as if they had been to the ancient city of Lijiang through the water cart. Beside the waterwheel, there are also signs of world cultural heritage, and it has become a necessary place for tourists to take pictures and remember. So there's always an endless stream of people here.
