Dashuhua, literally translated as "striking tree flowers," is presented in the form of molten iron being flung against the city walls to create showers of sparks. With a history of over 500 years, "Dashuhua" has been listed as an intangible cultural heritage in Hebei Province. CGTN's Mike Fox and Zang Shijie experience this classic fireworks-like show in Yuxian County, Zhangjiakou in north China's Hebei Province.
