It's July now, the hottest time of the year. The temperature of this year is higher than usual. I have heard a news that the temperature somewhere rised up to 42 degress Celsius. Pets don't want to put their paws on the burning ground. Some influencers driectly fries eggs on the ground. So, people who are just suffering from hyperthermy really want to go some places where the temperture is low around 20 degress. In fact, there are many cities where people can enjoy a nice and cool summer. You just need to hop on a train moving toward to the west od China. Sooner or later, you will find these cool and green worlds which are full of blue sky, cool temperture, green lakes and trees. They locate in the plateaus where people seldom experience hyperthermy. Many ofthem have a common called the cool capital of China. So, the best place to visit really depends on the weather.
