In 1998, Jiang Wancheng returned to Lengwu Village, where his father planned to transfer Suanzaogou at a low price to fruit buyer Hou Sanwang. While the villagers all felt the wild jujubes were sour, astringent, and hard to sell, Jiang Wancheng set his sights on the unique fresh-keeping conditions of the spring water and cold fog, targeting business opportunities in jujube drinks, jujube paste, jujube tea gift boxes, and rural tourism. Teaming up with returning food R&D specialist Lin Zhi, he pruned fruit trees, graded harvests, developed products, secured county orders, spearheaded a cooperative, and built a cold storage facility, creating the Lengwu jujube brand. Despite Hou Sanwang's continuous price suppression and disruption, the villagers shifted from skepticism to unity. The Lengwu jujubes were successfully sold to the provincial capital, and the lights on the Jujube Blossom Scenic Slope lit up.
