He would bathe twice a week until like 2005 because he thought domestic hot water was decadent and should sparsely be used. For most of his life, communal bathhouses were the norm in our part of China, so he'd go there every other day and just use cold water and soap if he couldn't be bothered. I have vague memories of some of the last ones in Wuhan being phased out in the late 90's so there was a few years there where my aunt would have to put up with terrible odour from the chain-smoking alcoholic, esp since how humid Wuhan is in the summer. Also it turns out lye soaps aren't too good for the skin after prolonged use, he had dry ass skin until my cousin swapped him over to some softer soaps.
