When the Mid-Autumn Festival approaches, snow-white leek flowers quietly bloom in Longtan and Daxi, attracting cyclists who pause to enjoy the pastoral scenery. The snow-white leek flower sea, which lasts about a month, can be admired from the Yonghe Bicycle Path nearby. Gazing at the vast expanse of leek flowers resembling a snowy blanket swaying in the wind, it’s a scene full of northern charm that’s truly enchanting.

Leeks begin to bloom white flowers in autumn, marking a brief lull in farmers' production and sales work. In specialized leek-growing areas such as Ruiyuan and Zhongxin, a vast white landscape emerges, with swaying white blossoms dancing in the wind as if celebrating the arrival of autumn—like a festive occasion rejoicing in the bounty and joy of the harvest. Daxi Town has approximately 100 hectares of leek fields, with 70 hectares concentrated in the Zhongxin specialized growing area. As a result, walking along Zhongzhuang Street, one can smell the fragrant aroma of leek flowers.
