World's first captive-bred panda twins of this year were born at the Chengdu Research Base of Giant Panda Breeding in southwest China's Sichuan Province on Tuesday. 

Fu Wa, the mother, and her two cubs, both male, are in good health. The first cub was born at 12:57 a.m. and weighs 159.8 grams, while the younger one was delivered at 15:10 p.m. and weighs 119.5 grams.

The cubs cried loudly upon birth, an instinct to attract their mother's attention. 

"The twins are the earliest pair of pandas born at the base," said Wu Kongju, an expert at the panda breeding base.  

"It is very rare for pandas to have estrus in winter and give birth in spring. This is the fifth time Fu Wa has had a baby. So far, 17-year-old Fu Wa has given birth to eight panda cubs," said Wu. 

Amid the epidemic, a large amount of bamboo has been stored with an emergency bamboo supply plan formulated as backup.
