(The picture of the panda cub)

Haizi, a 23-year-old giant panda (about 80 in human years) gave birth to twins at Wolong National Nature Reserve in Sichuan on July 30, making her the world’s oldest new panda mom, according to CNTV.

The two cubs, a boy weighing around 123 grams and a girl weighing around 175 grams, are in a “perfect health” and are being looked after by their mother.

Haizi was rescued from the wild in 1994 and gave birth to twins in 2013. She was sent to Wolong to spend her remaining years in comfort but showed a courtship behavior this spring. A date with male panda “Yibao” was arranged and four months later she was a mom again.

An expert from the China Conservation and Research Center for the Giant Panda said most pandas are reproductive until about age 20.
