The low temperature of about - 30 ℃ makes the weather frosty. Large fish more than half a person high are inserted in the ice bucket. Colorful river fish are arranged layer by layer. The sound of hawking rises and falls one after another. The scene is spectacular. On January 11, Hezhe people were catching in the winter in East Lake, Fuyuan City, Heilongjiang Province. Wang Jianwei, a reporter from the Xinhua News Agency, took this photo of Fuyuan City, Heilongjiang Province, the "East Pole of China". It is known as the "capital of freshwater fish in China" because it is located at the intersection of the two major water systems of Heilongjiang and Wusuli River. Fuyuan was originally named "Iliga", which means "golden fish beach" in Hezhen language. The green and pollution-free water environment provides unique conditions for the survival and reproduction of cold-water fish here. The local area is rich in 105 species of fish in 21 families, including "three flowers, five luo and eighteen zi". It is the home of sturgeon and salmon in China. The sturgeon for sale was shot at the "East Polar Fish Market" in Fuyuan City, Heilongjiang Province on January 9.

Hundreds of orders have to be sent out a day, which can be sold as far away as Guangzhou, Hainan and other places." Zhang Yunhao said. "Our ancestors made a living by fishing. Our generation began to sell fish and extended the industrial chain." In order to better balance their careers, the couple simply ate and lived in the fish shop when they were busy. "I bought more than 10000 yuan of express boxes before, which is not enough. I have to go to the express delivery point to buy some more. I have to take hundreds more woven bags." At lunch time, they summed up their next arrangements. There are nearly 100 merchants on both sides of the "East Polar Fish Market", which is more than 100 meters long. Although the water outside has become ice, the guys in the fish shop are busy and hot. The courier drove around the fish shops to collect the packed fish and send it to the motherland in all directions to add a delicious meal to the festival table.
