Regarding the matters of the Gu Family, Yang Qingyin didn't know much; she and Luo Ziling only discussed what Ye Xiaoli had hastily found out. Therefore, Luo Ziling's doubts weren't completely resolved.
Although Yang Qingyin had Ye Xiaoli investigate quite a few things, there were still many aspects she didn't understand and hadn't completely figured out.
However, during the meal with Luo Ziling, Yang Qingyin still learned a lot about traditional medicine, such as the history of the 'Heavenly Acupuncture Bronze Man,' the details of 'The Illustrated Manual of Acupuncture Points on Bronze Figures,' and the deeds of Wang Weiyi, among other things.
Luo Ziling also talked about the 'Collection of Prescriptions' his grandfather had compiled and generously handed the recipe book over to Yang Qingyin for her to look at.
