Recently, the 12th Red Leaf Festival of Pofengling Scenic Area in Huangshandian Village, Zhoukoudian Town, Fangshan District opened. This place is praised by the China National Geographic magazine as the most spectacular mountain red leaf landscape in North China. In the next month, the entire secluded mountain valley will be rendered into a "watercolor painting" by more than 200,000 thriving cotinus coggygria, presenting a magnificent view of colorful forests.

The Pofengling Scenic Area is built on the mountain. Tourists can climb up to the mountaintop along a 6,000-meter-long stone step trail to enjoy the magnificent red leaf scenery. Little known is that Huangshandian Village did not use large machinery to build this trail. All building materials were manually carried up the mountain by people and donkeys. "The beautiful scenery bestowed by the mountains is the fundamental source of our income. We cannot destroy the mountain just for the sake of speed and convenience," said Zhang Jingang, the secretary of the Huangshandian Village Party branch and director of the village committee. The green mountains and clear waters are worth more than gold and silver. The Pofengling Scenic Area and homestays bring in more than 20 million yuan in income for the village collective every year on average.

At 1700 meters on the stone steps trail in Pofengling Scenic Area, there is a charming lake called "Yun Lake". The lake water is clear and transparent, with a water surface area of more than 3000 square meters, a depth of 0.8 to 1 meter, a water storage capacity of 3500 cubic meters, and an altitude of 300 meters. It is located 100 meters west of the famous "Cotinus Coggygria King" in Pofengling Scenic Area, and is the best place to enjoy the lake view, the main peak of Pofengling, and the distant view of Guancai Mountain.

When visitors walk up this stone step trail, besides enjoying the scenery, they can also read the exhibition boards along the way to understand the spirit of the "Red Backpack". In the 1960s, the movie "Red Sorghum" caused a sensation. It tells the story of a member of a supply and marketing cooperative in a mountainous area of North China who travels between dangerous mountains and perseveres in delivering goods to the door with a backpack, regardless of wind and rain, to bring daily necessities and production materials to the villagers. The place where the story takes place is Huangshandian Village.
