Due to the inaccurate navigation positioning, I found the positioning point, but the locals said it was not here, drew a picture, continued to go, intermittently asked 7 people to find a few hundred meters away, take pictures and leave, there is no trace, just a graffiti wall. It is recommended to modify the navigation positioning, it should be set to the language school by the river, otherwise it will harm the people who can't find it later.
