There is a very special place in China. It is the Qinghai-Xizang Plateau. In the place, the weather is very changeable. You can experience “four seasons” in just one day.
“Spring” morning
The Qinghai-Xizang Plateau has a cool early morning. When the sun comes out, the weather there becomes warm, just like spring. So 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 like it's summer because it is very hot. The sun shines brightly. So you'd better wear sunglasses. It rains sometimes, but the rain doesn't last long. If you are lucky, you may see rainbows(彩虹). They usually come out after the rain.
“Autumn(秋季)” afternoon
You have to be careful about the weather in the afternoon. As the sun sets(日落), it becomes cool again, just like autumn. If you don't keep warm, you may catch a cold(感冒).
“Winter” night
At night, the temperature gets very low, just like winter. You need to wear warm clothes. And don't go out because it often rains at night.
