It says: “Growing in the wild the Rosa roxburghii tratt refuses to be potted, and though with bright color its flower won’t go inside vermilion gates. However, with water in dragon well the fruit is made into wine, which is honored to be supplied to the emperor.” Zhao Yijiong was the first national number one scholar from Yunnan and Guizhou provinces who have passed the ancient provincial civil service examination. The poem was written in his childhood, which showed his great talent at an early age.

He aimed to find more wild food resources that can be used to relieve the public’s pain of suffering from starvation and help the people in misery. In his research, he found out that the wild Rosa roxburghii tratt in Guizhou contains rich vitamin C, vitamin P and vitamin K. Among these, vitamin C is as high as 1980-3750mg in per 100g pulp, way higher than in any other fruits and vegetables. And this has caught great attention from the academic circle both at home and abroad.
