Is it worth going to the Bayinbulak Grassland around September 10?

Question 1: It is better to go to Bayinbulak and Nalati in July and August. In September, the weather is already cold and there is not much grass on the grassland. <br/>Question 2: Bayinbulak is a large grassland similar to Inner Mongolia, and has lakes, while Nalati is an alpine grassland with mountains, valleys and rivers. If you have been to Inner Mongolia before, you can only go to Nalati, otherwise two It's good to go everywhere.
