A pack of newborn panda twins will greet visitors to the Chengdu Research Base of Giant Panda during the seven-day National Day holiday that starts on Oct 1.

"They can have a close look at the twins in the nursery and be separated from the cubs from a glass window only," according to Zhang Zhihe, chief of the center in Sichuan province.

Sixteen cubs in eight pairs of twins were born at the center this year.
