Dalian to Inner Mongolia to play, self-driving, what are the good routes recommended?

There are roughly two directions from Dalian to the nearest grassland, one is Chifeng Hexigten Banner in the west, and the other is the grassland in the northwest of Tongliao in the north. It is difficult to drive to the grassland in both directions in one day. You can usually stay in Chifeng or Tongliao for one night, and you can go to the grassland at noon and afternoon the next day. Besides seeing the grasslands in the northwest of Chifeng, you can also visit Niol Lake, Baiyin Aobao, and even Ashatu Stone Forest and Huanggang Beam (the scenic spot at the southern end of Daxinganling). In the northwest of Tongliao, there are Zhu Rihe Grassland and Arukerqin Banner Grassland. Suggest going to Chifeng Keshiketeng Banner. However, the four-day time is tight, so it is recommended to increase the itinerary by one day. Along the grassland, you will see some yurts, where you can stay and ride horses.
