There is a very special place in China. It is the Qinghai-Tibet Plateau (青藏高原). In the place, the weather changes (变化) a lot in summer. You can experience (经历) "four seasons" in just one day.

 "Spring" morning 

The Qinghai-Tibet Plateau has a cool morning. When the sun comes out, the weather there becomes warm, just like spring. It's a good time to take a walk in the morning.

 "Summer" noon 

The weather at noon is very different from that in the morning. You may feel it like summer. Because it is hot and the sunlight is so strong. You had better wear sunglasses. Or it rains sometimes, but the rain doesn't last long. If you are lucky, you may see rainbows.

 "Autumn" afternoon 

You have to be careful about the weather in the afternoon. As the sun goes down, the temperature goes down. It becomes cool again, just like autumn. If you don't keep warm, you may catch a cold.

 "Winter" night 

 At night, the temperature gets very low, just like winter. You need to wear warm clothes. The rainy season is from June to September each year. It often rains at night.
