Pandas are black and white. They have big, round bodies and short tails. Their most distinctive feature is the black fur around their eyes, which makes them look like they are wearing big black glasses, very funny. Pandas mainly live in the bamboo forests in Sichuan, Shaanxi and Gansu provinces in China. They love to eat bamboo. They spend most of their day eating and sleeping. Although they are big and heavy, they can climb trees very well. Pandas are very important in the world. They are not only a symbol of China but also a precious treasure of the whole world. They play an important role in maintaining ecological balance. However, due to the destruction of their habitat and other reasons, the number of pandas was once very small. Thanks to the protection and care of the government and people, the number of pandas is gradually increasing now. In a word, pandas are so charming that I love them very much. I hope everyone can join in the action of protecting pandas and let them live happily in this world. 1 学科网（北京）股份有限公司 $
