China is improving its pandas' viability by giving them training and physical exercises.
Feeders in southwest China's Chengdu Research Base of Giant Panda Breeding would first hang food on a long stick and attract pandas to stand up to reach the food.
By persisting in the exercise, the rare animals have reinforced the strength of their hind legs.
"The hind legs play a very important role in their natural mating," said a feeder.
Baby pandas also need trainings like drinking milk or water from feeding bottles, and eating apples as well as steamed bun of corn.
But some are so cleaver that they soon found drinking while lying on grass is more comfortable than drinking while sitting, the feeders said.
Most of the time, elder pandas would like to tease the younger ones; however, once in a while, the latter, after being so teased, will choose to come together to "fight back," according to the feeders.
