The plot synopsis of the emperor’s sister-in-law Tian Osmanthus

During the Ming Dynasty, Tian Guihua (Fang Qingzhuo), a vegetable grower on the outskirts of the capital, accidentally saved a young man (Ji Chenmu) who was being hunted on her wedding day. Next, the boy and the groom Heidou (Chen Zheng) became brothers after eight worships. But the young man was the prince of the current dynasty who was framed and fled the palace to seek refuge in the countryside.

Tian Guihua and his wife, who are upright and vindictive by nature, were unknowingly involved in the internal fighting in the palace. There was turmoil, the flash of swords, bloodshed, and many crises. Tian Guihua firmly believed in the prince's innocence, refused to retreat, and helped the prince to clear up his grievances without hesitation. On the way back to the palace, there are many murderous intentions, traps at every step, and ambushes everywhere. In order to protect the prince, Heidou died unfortunately.

The internal strife in the palace was quelled. The critically ill emperor announced his abdication to the throne of the Supreme Emperor, and the Crown Prince became the new emperor. The new emperor conferred the title of "Emperor's Sister-in-law" on the new widow Tian Guihua, enjoying a unique status.

The emperor's sister-in-law was very unfamiliar with everything in the palace, as if Grandma Liu had entered the Grand View Garden, and made a lot of jokes. Guihua, who has a cheerful personality, always treats people with sincerity and love. She is open and aboveboard. But she could never adapt to the environment of the palace, and the affairs of the court were beyond the understanding of a country person like her.

Osmanthus decided to return to the folk and go sightseeing around. In order to protect the emperor's sister-in-law, the emperor specially arranged several servants with extraordinary intelligence and strong martial arts to accompany her.

The emperor's sister-in-law returned to the people, and she became an imperial envoy without an official and a patrol officer without a seal. During the journey, Guihua loved and dared to take care of all the ugly things that happened among the people, big and small. For example: stories about loyal ministers being wronged, malpractice for personal gain, avenging private vengeance, corruption and perverting the law, forcing good girls into prostitution, etc., which are closely related to the current social reality and the common people.
