A time-travel mirror connecting the Tang Dynasty and the 21st century initiated a time-travel collision between the little princess of Jinyang and Xiao Ran. In the cold winter of the Tang Dynasty, the little princess had a warm baby, a hot sleeping bag, thermal underwear, and a down jacket. As a snack, various candies, pastries, and milk tea snacks were naturally indispensable. Things that did not belong to the Tang Dynasty, such as potatoes, sweet potatoes, and corn, appeared in the Tang Dynasty.
