Xu Yan is an author about whom limited public information is available. Three of her works are included in the collection, spanning the categories of medicine and examinations. Among them, Advances in Modern Disinfection Science (Volume II) reflects her academic attention to the field of disinfection science, while the Shanghai-Style Chinese Medicine Internal Medicine Ding Ganren School Series—Yan Cangshan's Academic Experience Collection shows her involvement in organizing and passing on the academic legacy of Shanghai-style Chinese medicine.
