Worker Under the River Bed

After eight years of river improvement, this group of grassroots workers completed the impossible task in their dirty waterways. During the construction process, no matter it was windy or rainy or the sun was shining brightly, they always regarded this project as their mission. During the adventure and difficulties, we also saw their division of labor and trust in each other. This group of unknown people worked hard and made great achievements. Heroes, we should applaud them.
