The original name of the TV series Bathing as a Guardian is Great Plague 19 10, which is adapted from the historical event Northeast Great Plague 19 10. 19 10, the plague was prevalent in northeast China. Within a few months, tens of thousands of people were killed, which is likely to spread to Zhili, Shandong and Beijing. At that time, there was no specific medicine for this evil disease; If the epidemic is allowed to develop, Harbin may be destroyed, the three northeastern provinces will also be devastated, and China may become the second medieval Europe.

Lian Dewu, the first China doctor of medicine from Cambridge University, was appointed as the "Chief Medical Officer of Qing Dynasty" and rushed to Harbin to take charge of epidemic prevention in three northeastern provinces. After autopsy, the cause of the epidemic was determined, and through a series of efforts, the spread of the epidemic was successfully stopped, and the plague was defeated for the first time in human history.

In order to summarize and commend Lian Dewu's epidemic prevention experience and achievements, a landmark international academic conference was held in Fengtian, China for the first time, and Lian Dewu Wudang was elected as the chairman of the conference. He also became the first Chinese candidate for the Nobel Prize, and his 16-character working policy of "patient isolation, wearing masks, subsection martial law, disinfection and corpse burning" also became the main way to prevent SARS in 2003, which is still in use today.

Except for medical professionals, most Harbin people don't know the painful history a hundred years ago. Director Yinghai Deng hopes to eulogize urban heroes and inherit the "Liandewu Spirit" belonging to Harbin. The teacher of Guanghua College in Harbin discovered this disaster theme. The crew made a special trip to Singapore to visit Dr. Lian Dewu's eldest daughter and learned a lot of unknown historical facts.
