The Laobiangou Scenic Area is divided into two lines, one is the Phoenix Ding Ice Valley and the other is the old border ditch of Yonghe River. You need to hike to the top of the Phoenix to take a loop line. At the highest observation deck, you can see the Wuhua Mountain in the northeast autumn. Yongqi River is walking along the river, and the colorful maple leaves have increased a little bit because of the river water.
