Bathing is a basic physiological need of humans,rooted in the instinct for physical comfort.Historically,bathing was once ritualized.In modern times,bathing has returned to being a part of daily life.In modern China,most people bathed using locally available resources,with different bathing habits forming in various regions and environments.Bathhouses,emerging in modem society as communal bathing spaces,not only fulfilled the function of bathing but also carried social functions,reflecting the trend of modem society towards organization,where all aspects became integrated into a broader political framework.
