It is called Sanjiangkou, in fact, this is the intersection of Heilongjiang and Songhua River, and this third river is the same river formed after the mixing of the two. Because the sediment in the Heilongjiang water is black, and the sediment in the Songhua River water is yellow, they are not mixed after converging, but formed two distinctly colored water flows in the same river. More strangely, the two water flows stretched for ten miles without mixing, or retaining the original two distinctly colored water flows. This is a must-see place for soldiers in history. Standing on the riverside, near our shore is the Songhua River, and the other side is Russia. The two countries are bounded by the river. There is a cruise ship project in the scenic spot, and you can take a cruise to visit the entire river. There is an observation deck in the scenic spot, and you can clearly see the color of the intersection of the two rivers from above. There is also an iconic feature in the tourist area that there is a starting point sign for the same three roads. The Tongsan Expressway is also called National Highway 010 (or "National Highway 010 Line" and "G010 Line") which starts in Tongjiang City, Jiamusi City, Heilongjiang Province, and ends in Sanya City, Hainan Province, with a total length of 5,700 kilometers. It is the longest of the "five vertical and seven horizontal" main line planned by the state, and the only highway that runs through China's coastal areas. The tourist area is still a little distance from the city center, and there is a bus to get there. Taxi is estimated to be more than ten yuan at most. About ten minutes by car. There is a place to park at the door. The scenic area is relatively large, there is a small battery car inside, you can take two people, drive by yourself, 40 yuan for half an hour. The scenic spot is free, and you have to show two codes for epidemic prevention when you enter. Tongjiang City is very small, and it is still worth a visit here.

Tongjiang, I have been there twice, and these photos were taken for the second time. This is the starting point of the Tongsan Highway. The first time I came back from Fuyuan Heishizi Island to take the ferry to Tongjiang. The first impression of Heishizi Island in that year was to drive up without tickets. The first impression of Tongjiang was to eat fish. When I waited for the ferry, I bought the fish on the riverside boat. The smallest one was also 4-5 catties. After arriving in the city, I found a restaurant to process three dishes, one of which was sashimi, the Hezhe family eats, called Talaha, the name asked people several times to remember.

In fact, there are only two rivers. This is the starting point of the same three roads (the road to Sanya), and the Hezhe Museum in the square is worth seeing, but the location is a bit hidden. There is also a customs anti-smuggling pier that is very beautiful.

Heilongjiang Jiamusi Tongjiang Sanjiangkou, here is the starting point of the same three roads, that is, the starting point of the same river to Sanya, here is a place worth visiting
