I heard that Heihe City in Heilongjiang used to be Russian, so you can go there without a visa and passport. Please explain in detail. I'm going to Russia from Heihe.

Don't go private! ! ! I have lived in Heihe for many years and have never heard of success without a passport. On the contrary, I have seen some people swim over, disappear for a few days and then be sent back. When I came back, I was still wearing big shorts, and I was in a trance when I was interrogated by the Russian side! It costs more than 100 yuan to get a passport, and it will come down in two weeks. Then you can play how you want, don't worry!
