Chen Yi-tsung felt that the most difficult part was judging the length, breadth and thickness of the nearly 1000 newly made pieces. Any errors in calculating these dimensions would not only mean that they would not fit together with the original parts, but would also create a difference in the roof inclinations of the front halls and the main hall so that they would not join correctly either.
陳益宗覺得最難的地方就是推斷那些上千件新做構件的長度、寬度、厚度，每一個構件的尺寸只要略有錯誤估算，不僅無法和原件配合，還會導致前殿與正殿的坡度不合，無法相連。
