Speaking of everyone in Heilongjiang is very familiar, if you want to ask where the source of Heilongjiang is? Do you feel a little confused? After we came out of the Arctic Village, we drove along the forest road to explore the Luoguhe Village hidden in the depths of the Daxinganling. This is the source of the Heilongjiang River. The village is simple and quiet. It takes a half-hour ride on the river by the yacht. It is Sino-Russian. The border pillar 133 on the border line is really only one water away from Russia. There is a source outpost at the other end of the village. The sentinels guard the security of the border day and night.
