Liu Wenying, a modern nursing supervisor, died unexpectedly. Once she traveled back in time to the ancient dynasty, she became a miserable woman who had just lost her husband and was cruelly expelled from her husband's house. In order to support her infant daughter, she had no choice but to apply for a job at the Yuguo Duke's Mansion. Relying on her solid and professional nursing skills, she was successfully selected in the rigorous assessment and was able to take her daughter into the mansion with her. After entering the mansion, she took good care of the young master in the mansion and made him healthier day by day. She also used her nursing knowledge to take good care of the old lady who was paralyzed by a stroke. Her skills in recuperating gradually spread throughout the capital, and even the eldest princess and a group of imperial wives came to ask for her help in recuperating her body.
