Ling Yuntai's record

Ling Yuntai's balcony is exquisite. Before construction, all the wood is weighed (so that the weight of the wood used on all sides is equal), and then the balcony is built, so that the weight on all sides is not bad. Although the balcony is high and steep, it often swings with the wind, but it is always impossible to collapse. Wei Mingdi boarded the Yuntai Mausoleum, fearing that it was in danger. Plus, he supported it with big wood, and the balcony collapsed immediately. Critics say it's because of weight deviation.
