Wang Yingluo needed a good reputation.
The more notable, the better.
In later generations, even elementary school students would know about "The Empress's Medical Book," and some scholars claimed that Huaxia's standing as the most medically advanced country in the world had a lot to do with Empress Murong.
It's undeniable that these simple medical knowledge entered every household, teaching the ignorant how to deal with common injuries and illnesses. According to the prescriptions, one could obtain medicine without spending the silver coins needed for seeing a doctor, nor would it delay treatment.
With nearly a thousand years of accumulation and inheritance, almost every citizen of Huaxia had some understanding of medicine. Seriously speaking, indeed, it was Murong Jiu's contribution.
Therefore, even after so many years, future generations would still remember Empress Murong, allowing her to remain illustriously renowned for centuries.
