When Lin Wanwan was in Chang'an, she once visited the acupuncture master Zhen Quan with Sun Simiao.
This divine doctor, already in his nineties, is renowned for his acupuncture techniques for generations.
Most of Lin Wanwan's acupuncture skills were learned from his disciple, Chen Liang, and upon meeting the divine doctor himself, she naturally performed the disciple's ritual.
However, the divine doctor was now old and rarely practiced acupuncture. Even the royal assignments he could resign from, he did, and naturally, he did not have the energy to personally instruct Lin Wanwan.
Fortunately, through the old Sun and the "Barefoot Doctor Manual", Lin Wanwan had the opportunity to borrow and transcribe his works such as the "Needle Scripture", "Mingtang Human Figure Map", "Acupuncture Formulas", and "Vein Classics".
These precious Chinese medicine books have unfortunately been lost, and only parts have been incorporated into other medical texts that have been passed down.
