One of China's seven rivers, Heilongjiang, the largest tributary in China, does not need tickets. The first time I came to Harbin, I saw the frozen Songhua River. I heard singers watching it on the Songhua River and TV. This time, standing on the Songhua River in person, I felt really amazing. The whole river was frozen. There were people driving through the river, skiing games and pulling carts. This ice dog has a nice name. Alaskan dog, especially cute and fierce, pulls people on the ice and runs on the Songhua River. Many recreational items on the river are charged, but they are not expensive. When you come to the northeast, you should try to play on the Songjiang River for more than 20 degrees below zero. This can not be felt in the south. The classic section here is near the Central Street. You can see it on foot through the flood control Memorial tower.
