Tong Yue'e, a 58-year-old villager, cultivates herbs in December to be transplanted onto polluted land in Huanjiang county, the Guangxi Zhuang autonomous region. After it is transplanted, the plant will absorb heavy metals that contaminate the soil. Much of the land in the area was contaminated by residue left after a flood in 2001.
