Introduction to Yudao Liuxiang: In the area from Haidian to Yuquan Mountain, during the Kangxi and Qianlong years, there were more than 10,000 acres of imperial rice fields in the west of Beijing. Emperor Qianlong's poem "Wanquan Suburban Travel" wrote: "It is suspected that the mountain village is a water town, the seedlings are as low as the rice seedlings are yellow. The green poplars are ten miles away, the sound of cicadas is boiling, and the refreshing wind carries the fragrance of porridge." Now a park has been specially opened here. In a rice field, every Beijing Rice Harvest Festival, the rice plants are swaying, the golden ears are fragrant, and people are harvesting with sickles, experiencing the hardship and joy of labor.
