The background is set in the Yongle period of the Ming Dynasty, in the Prince Jing's Mansion in Suzhou, Jiangnan, far away from the disputes in the capital. The whole process is mainly about "daily life in the palace + Jiangnan market + light royal socializing". There is no life or death crisis, no vicious female supporting characters stalking, and no power intrigues. All conflicts are resolved in a funny way, focusing on the contrasting laughter of "modern thinking collides with ancient feudalism".
