Qiantang River Bridge, Five Elements Lack of Fire
It is said that this is to celebrate the first bridge built under the leadership of Mao Yisheng China's first modern bridge - the Qiantang River Bridge was built. But not long after it was built, the Kuomintang army blew it up again in order to prevent the Japanese attack (and it was Mao Yisheng who reluctantly chose the blasting point, salute!), so it was said that the "Five Elements Lack of Fire" was applied.
