The license plate test route is a great test of physical strength and endurance.

The legendary Beiling Shuangdu, the "test line" in the mountains, mainly tests your descent skills on gravel roads. You have to go up and down many hills, all on gravel roads, using both your hands and feet. Routes where you can get injured easily if you are not careful are very exhausting. But the scenery is beautiful, I think it's worth returning! Walk from day to night, remember to bring enough water!
