Can I go to Moscow by boat from Jiamusi or Harbin in summer? Where can I buy a boat ticket? Where is the most convenient place to go?

If you can't take a boat, Harbin's route has long been blocked by Jiamusi, and there are sometimes no passenger ships between Jiamusi and Russia. The safest way to go to Russia by boat is to go directly to Tongjiang or Fuyuan, where there are ships to Russia, and the ships can go to Khabarovsk, Russia. I suggest you fly directly from Beijing to Jiamusi and then take a bus from Jiamusi to Tongjiang or Fuyuan. In fact, if you travel, you'd better take Suifenhe, fly directly from Beijing to Mudanjiang, and then report to Mudanjiang.
