Two men want to travel in August. Is there any good place to recommend?

Hulunbeier grassland in the city is one of the four largest grasslands in the world and is called the best grassland in the world. Prairie people are good at singing and dancing, and they are hospitable. When they come to Hulunbeier, they will definitely feel the friendliness and enthusiasm of the local people. The average temperature here in August is only 16℃-2 1℃, which is the best time to escape the summer and enjoy the beautiful grassland scenery.
