“廿四雄师奋战勇，誓锁蛟龙战旗飞。严寒酷暑热汗洒，星夜挑灯迎晨晖。”———这是北京市老领导王宪同志生前于１９９０年２月为密云水库建成３０周年写下的诗句。这既是密云水库建设者们的精神写照，也是建国初期首都水利建设者的精神写照———艰苦奋斗，无私奉献，团结协? “The four heroic warriors fought bravely, and swore the dragons and flags to fly. The cold, the heat, the sweat, and the starry nights, the light of the morning and the night.”—This was built by the old leader of Beijing, Wang Xian, in February 1990 for Miyun Reservoir. Anniversary verses. This is not only a spiritual portrayal of the Miyun Reservoir builders, but also a spiritual portrayal of the capital’s water conservancy constructors in the early years after the founding of the People’s Republic of China: hard struggle, selfless dedication, and solidarity?
