China seems to be having good luck in recent efforts to preserve the endangered giant panda.
A set of twin cubs was born at western China's Giant Panda Nature Reserve Saturday, the fourth pair since August.
China's official news agency says they are in good health.
Chinese government figures say there are only about 1,000 giant pandas living in the wild, and 140 in captivity around the world.
Reserve zoologists say they moved in to care for the cubs, weighing 150 and 168 grams, after the mother left them after the birth. The Nature Reserve is home to 67 pandas that are more than six-months old.
