"...他们的所谓建设"
You're silly to brutally over-simplify an extremely comlex era of Chinese history, during which China had to deal with world economic recession and naked aggression of heyday's Imperial japan. This is typical hindsight 20/20 from a naive boy like you.30年已经不再有外在危险的新中国经济那种衰落破败的悲惨景象,人们不是记忆犹新吗? lol
