CHENGDU, July 13 (Xinhua) -- Lin Bing, a giant panda born in Thailand and returned to China in 2013, gave birth to twins last week, the Chinese Giant Panda Protection and Research Center announced Thursday.
The cubs arrived about seven hours apart last Saturday. The female cub, weighing 170 grams, was born at 8:17 a.m.; her brother, weighing 159 grams, arrived at 3:08 p.m.
Both of the cubs and their mother are in a healthy condition.
According to base staff, Lin Bing had mated with two male pandas before showing signs of pregnancy. The father of the cubs has yet to be confirmed.
The twins are the first pandas born at Sichuan's Shenshuping protection base in the reconstructed Wolong National Nature Reserve after the habitat were severely damaged in the 2008 Sichuan earthquake.
The earthquake left one panda dead and another missing.
Born in May 2009, Lin Bing is the daughter of giant panda couple "Lin Hui" and "Chuang Chuang".
As the first giant panda born in Thailand, Lin Bing has become one of the most popular animals in the country. In 2015, she also gave birth to twins.
