Staff members clean the Haihe River in north China's Tianjin, June 27, 2019. Haihe, known as the city's "mother river", runs for more than 70 km from Tianjin Municipality to Dagukou where it empties into the Bohai Sea. Nowadays nearly 30 bridges span across Haihe and many skyscrapers stand by the river. Haihe has become a major landscape belt in Tianjin, with its clear water and beautiful view along the bank.
