论曰昔人论香港脚，谓脾受阳毒即热 ，肾受阴湿即寒痹，是知香港脚之病，脾肾得之为多
也，今变成水肿者，亦缘脾肾俱虚之故，盖肾虚则不能行水，脾虚则不能制水，故水气散溢，
渗于皮肤，流遍四肢，所以通身肿也。

Discussion states: Ancients discussed Hong Kong foot (a disease characterized by swelling and pain in the feet), stating that when the Spleen is affected by Yang toxicity, it manifests as a Heat syndrome; when the Kidney is affected by Yin dampness, it manifests as Cold Bi-syndrome. Thus, it is known that Hong Kong foot disease is mostly caused by damage to the Spleen and Kidney. The current transformation into edema is also due to the deficiency of both the Spleen and Kidney. Generally speaking, Kidney deficiency fails to transform water, and Spleen deficiency fails to control water, causing water qi to scatter and overflow, seeping into the skin and flowing through the four limbs, thereby resulting in generalized edema.
