During the Northern Song Dynasty, in the bustling city of Bianjing, there lived a smart and playful girl named Su Miaoyin. She is as smart as ice and snow, her head is full of strange ideas, and she is proficient in poetry, music, chess, calligraphy and painting, as if she is a talented woman who stepped out of a painting. What's more interesting is that she is also a complete foodie. When it comes to food, her eyes will light up. She is especially fond of the sweet and delicious candy men on the streets of Bianjing. Every time she passes by the candy man's stall, she can't move.
