On the snowy road to exile, Shen Qingdai clutched the family medical book her father gave her before his death. Once the daughter of a royal hospital, now she is shackled, and her destination is Hanshi Pass in the bitter cold of northern Xinjiang.
In the dilapidated exile village, epidemics raged and there was a lack of medical treatment. Officials looked coldly on him, and villagers ostracized him. She pulled out the silver hairpins from her hair and used them as needles, picked wild grasses as medicine, and fought for every life in despair. From being isolated and helpless to winning the first trust, every step is in the mud.
The cold-faced guard Xiao Heng's acquiescence, the poisonous-tongued military doctor Lu Yan's doubts, the war and scarcity at the border... Are all mountains she must climb. Improve wound medicine, establish isolation, and even venture behind enemy lines late at night to retrieve life-saving medicine. She turned the leaky temple into the Ji'antang, the last resort for the wounded in the war.
From the wind and snow in the prison to the beacon smoke at the border, watch how an exiled medical woman uses her medical skills and tenacity to light an everlasting lamp for herself and others in the bitter cold.
