It's not a weekend, there are almost no people here. Because of the epidemic, the small trains are not open, and it is still possible to step on the railway. Many places are under construction, and there are not many roads to walk. Next to it is the Garden Expo Park surrounded by fences, and you can clearly see the Garden Bota. I also saw a large tank train passing by the bridge. Transportation: There is a parking lot opposite the northwest gate, 10 yuan is unlimited time.
