Pandas live in the mountains of Sichuan, Shanxi and Gansu in China. They are fat. They are black and white. They are very cute. They've got two big eyes and a short tail. Pandas can climb and swim. They love bamboo. They start eating bamboo when they are about 6 months old. They eat for 12 hours a day. Now there are only about 1, 900 pandas in the wild（野外）. Some of them are in danger of dying out（灭绝）. We should help and protect（保护）them.
