Bingyan, the Healer

Pure Historical Romance: A Female Lead Who Knows Medicine or Is a Pharmacist

Looking for books similar to Three Thousand Miles of Drifting Light. I hope it involves an ordinary family, with the protagonists opening a medical clinic or running a family pharmaceutical business. Preferably not the sort involving high-ranking nobles and officials. No rebirth, transmigration, or System! Something like Three Thousand Miles of Drifting Light would be ideal. An alternate world is fine too. No specific preference.
