Here is the northernmost point of our country, 53°33'43'' north latitude. I remember that there was a standing stone monument with the words: Congratulations, find the North! Now this stone has been replaced and become the northernmost point in China. The rich river valley downstream of this beautiful river is his nomadic place. He also built a city on the wide ridge of the north bank of Heilongjiang: Albajin, so far the Russians still follow their names. That is the name Jacques that we are familiar with. However, in the winter, it became a fairy tale world wrapped in silver, and the branches of the distant hills were covered with a thick layer of snow. When you walked on the already frozen Amur River, the thick snow made a "squeaky" sound, and turned and looked, leaving only a few footprints.
