Was there popcorn in ancient times?

There has been popcorn since the Song Dynasty, which originated in China in the Song Dynasty. Fan Chengda, a poet at that time, mentioned the custom of popcorn in Wuzhong on the Shangyuan Festival in his Shihu Collection, and explained: "The fried glutinous rice is Ibrahimovic, named Bulou, and the number of glutinous rice is Beijingers." Why is popcorn called Bulou? Popcorn should imitate the sound of popcorn, because the local dialect calls the sound of thunder "grinding" Zhao Yi, a scholar in Qing Dynasty, recorded a poem "Blasting Buildings" in his Miscellanies of Exposing the eaves: "When you enter Dongwu Gate, 100,000 families break the valley and spend their youth. Put the golden millet in the pot and turn it into Bai Yuhua. Pink lady is a happy event, and the old man asks about his career. Xiao Lai decorated his son, and several pieces of plum blossoms were inserted into his temples. " The popcorn written by the poet is not only beautiful in writing, but also full of life interest. Fan Chengda recorded in "The Custom of Wu Jun": "Shangyuan ... exploded glutinous rice in a pot, named Bolou, also known as Mihua. Everyone blew themselves up to rest for a year. " On the occasion of the Spring Festival, Song people used popcorn to predict the good or bad of the year, and girls used it to ask their lifelong events. Song people added diet to culture, which enriched its connotation.
