a pair of panda twins were born to captive and wild parents on monday.
panda qiao qiao, 10, gave birth to the twins at the hetaoping panda base in wolong, southwest china's sichuan province.
one of the cubs is male and weighs 206.6 grams. the gender and weight of the other are unknown because it is so closely protected by its mother.
experts say it is very rare for a panda cub to weigh over 200 grams. rescued from the wild, qiao qiao grew up in captivity.
she was released back into the wild in march and mated with a wild panda in april.
