What is the best month to travel to Tongliao?

The solar calendar is the best in September and the most beautiful in early autumn. The most interesting first push is Dagou, in the back flag. It takes about an hour to drive from Tongliao. It is characterized by virgin forests, drifting and strong Mongolian customs. You can eat beef jerky and drink koumiss. No need for three days. Others include the White Pagoda in Kailu Yuan Dynasty, Naiman Palace in Qing Dynasty, the hometown of Zuo Xiaozhuang, grassland tourism in Zhaqi Mountain, and Kulun Fuyuan Temple. These don't cost much, that is, 1000 yuan. Personally, I think there is nothing interesting in Tongliao. Better not come. It used to be Horqin grassland, but now it's all yellow sand.
