"Their mothers will teach them how to find food and water and climb trees. Researchers will play a secondary role by providing the mothers with food when bamboo is scarce, and they will monitor the mothers and cubs," said Zhang Guiquan, deputy chief of the center.

To minimize the impact of humans on the cubs, researchers wear black-and-white costumes when providing physical checkups. They used to teach cubs how to survive in the wild. It took a lot of time and energy, but results were minimal.

Zhang Hemin, the center's chief, said, "Panda mothers are much better teachers than humans, because they have an innate knowledge of what to do in the field."
