Introduction to Weijiang Wharf: Weijiang Wharf was the largest tea distribution market in western Sichuan during the Tang Dynasty. It was called "Weijiang Grass Market" at that time. Jiezi's "Yongkang Tea" became the tribute tea that the imperial court used in exchange for military horses in the Western Regions. Almost all tribute tea was transported by water. This was an ancient water transport wharf at that time. With the improvement of land transportation, this wharf was gradually abandoned. Now it has been restored and rebuilt in recent years.
