Zhejiang’s 999th case of hematopoietic stem cell donation: identical twins matched to the same patient. Lan Jiang Tianjing and his younger brother Lan Jiang Diyi are identical twins born in 1999.

The blood sample and a hematology patient were successfully screened and matched at the same time. "I'm the older brother, I'll go first," says Lan Jiangtianjing. "Seeds of Life" was immediately sent to the transplant hospital to bring hope of life.
