Ok, it is a relatively large port between China and Mongolia, and you can see the boundary monument. The scenic spot is not big, it takes only an hour to walk slowly, it feels quite sacred. There is a China-Mongolia Commodity City at the door. It is estimated that the entry and exit gates are closed due to the impact of the epidemic, so I have not seen Mongolian residents who drive Mongolian license plate cars to promote goods. You can take a sightseeing train to the gate and go back and forth for 10 yuan per person.
