Dear Tom,
I'm glad to tell you about pandas. They are black - and - white animals with round bodies and big black circles around their eyes. They look really cute.
Pandas like to eat bamboo and live in bamboo forests. They spend most of their time eating and resting.
Pandas are very important. They are a symbol of China and are loved by people all over the world. Also, they are of great importance for scientific research.
However, the number of pandas is becoming smaller. We should protect their living environment and plant more bamboo to help them.
I hope you can come to China to see pandas one day.
Best wishes!
Yours,
