A 21-year-old German girl recently donated her "panda blood", or Rh-negative blood, on two occasions to save a 75-year-old woman in Wenzhou, Zhejiang province.

Christa Maria Idel, a language student at Zhejiang University, came to China to study for one semester, adopting the Chinese name Gao Xiongmao.

When she found out that her blood type is Rh-negative, she called herself Xiongmao, the Chinese name for panda.
