It can be said that foot bath is a comprehensive embodiment of Guangdong people's leisure, entertainment and health preservation methods, and has become a way of life. Besides heat in summer, the biggest feeling is heavy humidity, especially in the south, where the feeling of heavy humidity and hot flashes is even worse. And such a feeling of damp and hot flashes will bring more discomfort to the feet. So Cantonese people in the south love to soak their feet.
