Liu Qingyao, a heroine from the Tang Dynasty, accidentally traveled through time and transformed into a modern 6-year-old girl named "Little Tuanzi". Faced with the frame-up of her green tea stepmother Wang Yuanyuan, the negligence of her father Liu Zhigang, the troubles of her naughty stepbrother Liu Taotao, and the prejudice of her traditional grandmother Zhang Jinhua who favors boys over girls, she relied on the contrast between the wisdom of the Tang Dynasty and her identity as a cute baby to battle wits and courage in the collision of ancient and modern cultures. From kindergarten to family, she amazed everyone with her Tang-style etiquette, and resolved the crisis with Jianghu means. In the end, her family reunited and found a happy home that balances ancient and modern times.
