Abstract： WANG Shixiong was a highly influential scholar in warm-heat disease theory in modern Chinese history. His compiled work， Wen Re Jing Wei（Warp and Woof of Warm-Heat Diseases）， assembles the essence of warm-heat disease doctrine in the Qing Dynasty and reflects the academic perspectives of the traditional Chinese medicine（TCM）practitioners at that time on warm-heat disease theory. Through a systematic review of the discussions in Wen Re Jing Wei on yin-fluid injury caused by warm-heat diseases，this article elucidates the TCM pathogenesis of how warm-heat diseases damage human yin fluids. These pathogenetic mechanisms include： warm-heat and dryness pathogens directly damaging the yin fluid of the zang-fu organs； indirect damage to yin through interconnections between zang-fu organs； damage to yin fluid due to mistreatment or erroneous therapies； latent cold in the Shaoyin transforming into heat and injuring yin； and constitutional yin deficiency being further affected by external warm pathogens，thereby exacerbating yin fluid injury.
