Shen Yan, the "son-in-law" of the Su family, makes a living as a bookkeeper at the water transport terminal. He has a dull and tolerant personality, but is actually the only son of the framed former military minister Shen Jingzhi. Back then, Shen's father was framed for opposing the "legalization of the opium trade" of the great powers, and the entire Shen family was exiled.
Su Weiwan: Shen Yan's wife, a "helper" at the "Ren Xintang" Chinese medicine shop. She has a beautiful appearance but is taciturn. To the outside world, she only knows how to "prepare medicine and make soup." At the end of the Qing Dynasty, Western medicine poured in with the foreign powers. Qingnang Pavilion was coveted by the foreign powers and traitors for protecting the secret recipe of traditional Chinese medicine. Su's father was killed to protect the "Qingnang Medical Classic". Su Weiwan took the medical classic to avoid disaster and hide her medical skills.
