The Dayuan Dynasty has had five hundred years of imperial family members with an excess of yang and a deficiency of yin, until the descent of the one and only little commandery princess, Shen Yuyu, who right upon birth became the peerless darling in the palms of the entire court above and below. The Emperor and the Prince Regent vie in fancy ways to shower her with favor, six rugged older brothers protect their younger sister with all their might, and even the crown prince hostage from a hostile country willingly acts as a little follower. The little salted fish seemingly lies flat and gives up, yet stumbles accidentally into straightening the imperial court and enlightening high monks, using soft and cute power to protect the seas as calm and the rivers as clear, throughout a sweet, warm, and healing journey dense with humorous punchlines.
