Yang Qingyin revealed the information Luo Ziling wanted to know.
The Gu Family is also a renowned family of traditional medicine, with several generations engaged in medical research. By the time of Gu Changwei's generation, the Gu Family had been studying traditional medicine for over a dozen generations.
Members of the Gu Family have excellent medical skills, especially Gu Jian'an. A few years back, during a major epidemic treatment, his contributed prescription played a significant role, which led to him being personally received by leadership figures. One high-ranking official even wrote a character inscription for him, referring to him as "National Hero," and the medical hall originally named "Gu's Medical Hall" was thus renamed "Guoying National Medical Hall," with Guoying meaning National Hero.
"Do you know who wrote that inscription for Old Gu?" Yang Qingyin asked Luo Ziling with a smile, "I think you could guess it in a few tries."
