I think everyone in Daqing is a hero in the battle.
Wang Jinxi is just a typical example. Everyone faced great difficulties and made a choice, even sacrificing his own life.
My grandparents took part in the initial construction of Daqing.
As long as I can remember, I know that this is a heroic city, and every old worker is bleeding and sweating for national construction.
If you really want to know the history of Guan Yu Daqing, I think you should look up more information. If you have a chance, you will come to Daqing and go to the Iron Man Exhibition Hall, which will give you a more intuitive impression.
