In 1980, in a Mexico zoo, the giant panda Yingying gave birth to a baby named Xengli, the first giant panda cub born in captivity outside of China. However, the baby survived only nine days. Yingying, resident at Zoologico de Chapultepec "Alfonso L. Herrera," in July the following year gave birth to Tohui, a female cub, the first giant panda born outside China who stayed alive. Yingying's offspring included twins in 1985 and 1987. She died at age 14 in 1989. Tohui gave birth to Xinxin in 1990 at the Mexico zoo. Attempts to breed pandas in captivity began in China in 1955. The first ever live birth in captivity of a giant panda took place at Beijing Zoo, China, on 9 Sep 1963, when the male Ming Ming was born to the mother Li Li.«[Image: panda cub born in China in 2006, This baby weighed 218 grams at birth, the heaviest panda born in captivity.
