魏王的孙子一直以为垒筑中天台是一个绝妙的主意。中天台那高耸入云的形象,无疑具有极大的象征意义——其时,魏国的国运已江河日下,急需这样一个象征来振作士气。当时,天与地的距离是1.5万里——还未曾如今天这般远离人类而去,那么,中天台的高度就应该是7500里。宫廷工程师经过精密计算,并引进国外最新理论论证,发现台基面积只需魏国国土的二分之一,而非误传的那样,须以整个国家作为台基。 Wei Wang’s grandson has always thought that the towering roof is a wonderful idea. The towering image of the Central Tiantai undoubtedly has a great symbolic significance. At that time, the national fortunes of Wei had been going on for a long period of time. This kind of symbol was urgently needed to morale. At that time, the distance between heaven and earth was 15,000 miles - not so far away from human beings as today, then the height of the sky roof should be 7500 miles. After careful calculations and the introduction of the latest theoretical evidence from abroad, the court engineers found that the area of ​​Taiwan-based area was only one-half of the territory of the State of Wei, rather than a misrepresentation, that the whole country should be used as the foundations.
