Modern: An excellent attending physician in the obstetrics and gynecology department of a tertiary hospital, calm, professional and compassionate, who was exhausted mentally and physically due to an unexpected surgical dispute.
* Ancient times: Travel through time and become the only daughter of the owner of the "Jishengtang" drug store in a southern city in the Dayin Dynasty who died young. The original person died of illness shortly after his engagement was broken off due to his frail body and cowardly personality. After time travel, his body is still not strong, but his eyes are firm and his temperament is calm. Unexpectedly, she discovered an old and incomplete booklet left by her original mother, which recorded some folk gynecological prescriptions and delivery techniques (it became her early cover-up of "family origins").
