Dear Amy,

How are you? Last weekend, I went to Shanghai on my holiday. The weather there was very hot. We went there by plane. On the first day, we stayed at the hotel, because it was rainy. But we were happy to eat some Shanghai snacks（小吃）. Wow! They were delicious. On the second day, we went to Shanghai Zoo. It's the biggest one in China. We saw many cute animals. I love pandas best. The baby panda was very active, and the mother panda was quiet. They like eating bamboo.

Your friend,

Sarah
