I believe that you may not know the place name of Tongjiang. But there is a song that can make you listen to the melody and sing in harmony. It is the "Wusuli Boat Song": "The Wusuli River is long and long, the blue river waves, the Hezhen people spread thousands of nets, and the boats are full of fish..." Yes, this national golden song selected by UNESCO as a music textbook in the Asia Pacific region and sent into space is a landscape romance from the same river, and the Hezhen people sang the fishing song in the evening. The word "Tong" in Tongjiang City, Heilongjiang Province, obviously belongs to the common character of "vanishing in the public", but it has the qualification of "oracle bone" - one of the earliest Chinese characters in oracle bone inscriptions. From the beginning of character creation, the meaning of the characters has never changed, and its interpretation has always been like "Shuowen": "Hehuiya" From this, it can be reasonably inferred that the name of Tongjiang should be derived from the geographical description of the homeland of the early ancestors. The Song of Boats is a song that stands in the northeast with the Wanda Mountains of the Yangtze River. It goes up and down continuously and across the river. But when it reaches an alluvial plain, it is suddenly blocked by the Songhua River and Heilongjiang River. The ancient "Tianhe" river and the rugged mountains meet unexpectedly. As a result of this collision, mountains, streams, marshes, islands and other geographical structures are crowded together deeply and shallowly. However, the magic of nature has arranged all these things in such an orderly and rhythmic way that the mountains and hills suddenly open up, and the fields are as beautiful as brocade, and as colorful as oil paintings. Just as the Hezhe people's "Marriage Order" (folk song) sings: water is the skirt of the mountain, and stone is the skeleton of water. The resources and products, crops, farming, fishing and hunting, regional scenery, living customs, folk tales, etc. on this land are all "the same as the river, and all come from the river". Therefore, it is reasonable to say that this landscape was named "Tongjiang". No matter how beautiful a map is, it is nothing more than a combination of symbols such as mountains, rivers, passes, lakes, islands, and cities. Rivers run through the land, water flows through the mountains and mountains. Those who "share the same river" are not only geographical descriptions, but also have surging historical memories. Standing at the watchtower of a Jiejin whistling post in the northern frontier defense, looking across the two rivers, the torrential tide converges, and an impassioned and sad song suddenly comes to my mind. This is not the river, but the endless blood of heroes. "Mo Rigen" sings a long story about Tongjiang, which has a long history of Zhuang's thousand years of origin. Its profound ancient charm can be seen in Zuo Zhuan: "Sushen, Yan, Bo, our northern land." About 3000 years ago, this land near mountains and rivers belonged to a tribe called Sushen (according to the custom at that time, the tribe was named after the leader). This Sushen was obviously a leader with vision and pattern. Although he was far away, he chose to present the "important instrument" of the tribe - the arrow and stone bow to King Wu of Zhou to show his submission to the Zhou Dynasty. In the long history that followed, there were records of "Sushen's guests" and "coming to the court" in such historical records as Han Shu, Wei Shu, New Tang Shu, and Yuan Shi. Tongjiang sent envoys to the Central Plains to pay tribute every year, so that people could enjoy the years of stability and peace. The peaceful environment of "hunting along the mountain and fishing along the river" has made this place a breeding home for migrants
