As the saying goes, it's not rocket science that's the hard part, it's political science, convincing the politicians that they need to fund this adequately, whatever it is that you think it might cost, it's probably actually going to be more.
俗話說,火箭科學不是最難的,是政治學,說服政客他們需要足夠的資金, 不管你認為這可能要花多少錢,實際上可能會更多。
