In 1990, the National Shankou Mangrove Ecological Nature Reserve was established in Shankou Town, Beihai City, south China's Guangxi Zhuang Autonomous Region. Mo Jirui, who grew up in this mangrove forest, is the most senior forest ranger on the premises.
Many of the trees and shrubs in the reserve have been planted by Mo, who is also an expert on the conservation techniques of different mangrove species. At the age of 66, he continues his work, guarding the mangrove forest he so much cherishes.
