Every year around the Mid-Autumn Festival, a sea of snow-white leek blossoms quietly blooms in Longtan and Daxi, attracting many cyclists to stop and enjoy the pastoral scenery. The snow-white leek blossom sea, which lasts for about a month, can be admired from the Yingge Bicycle Path nearby. Gazing at the vast expanse of leek blossoms spread out like snow on the ground, swaying in the wind with a distinctly northern charm, one can't help but be enchanted.

Leeks begin to bloom with white flowers in autumn, and the work of farmers in production and sales also temporarily winds down. The specialized leek-growing areas in Ruiyuan and Zhongxin are blanketed in white, with swaying white blossoms dancing in the wind as if celebrating the arrival of autumn. It’s a lively festival-like celebration of the joy of harvest. The leek cultivation area in Daxi Town covers approximately 100 hectares, with 70 hectares concentrated in the specialized leek-growing area of Zhongxinli. As a result, walking along the streets of Zhongzhuang, you can smell the fragrance of leek blossoms wafting through the air.
