When Tao Tao was young, she was abandoned by her birth mother in the deep mountains. Fortunately, she was possessed by the power of a Qilin, saved Pei Mingyu, the heir of the Marquis estate, and was adopted as the Marquis estate's foster daughter. She can communicate with all beasts, using the assistance of animals to clear the grievances of the eldest branch, resolve the estrangement between the Marquis and his wife, make the vicious Liu Shi reap what she sows, and guard the peace of the Marquis estate. Later, Tao Tao's true princess identity was exposed, coinciding with the invasion of foreign enemies. She commanded all beasts to protect the country and its people, and was deeply loved by the imperial court and the common people alike for her sincerity and ability.
