Zeng Jingxin, a member of Jiufeng Forest Farm in Shanggao County, planted mint in a dry land of 4 mu in the past year in 1983, harvesting 70.7 pounds of peppermint oil and earning 883.75 yuan, with an average output value of 220.9 yuan per mu, higher than that of sweet potato in the past More times.
