It took almost nine hours to complete the Changpinggou Muzongzi round-trip hiking challenge. At 8:40 in the morning, I started from the Lama Temple. I walked all the way to take pictures. At 12:40, I went to the end of the plank road. The road to Muzongzi was really not easy to walk. It is best to wear outdoor thick soles. At 2 pm, I went to Muzongzi to rest for half an hour and began to return. On the way, I encountered heavy rain, and walked to the last hour. I finally struggled to return to the entrance. After the rain, I turned back and saw the most beautiful Siguniang Mountain. The four sisters were unobstructed.
