Compañero de Baño (2020)

-Chinese language films that take place in a bath house
-Owner is at risk of losing his bath house and struggles to train someone to maintain it/help him

One of subplots is rather similar - "fake" (grand}sons taking care of their "fake" old (grand)mothers with Alzheimer's

Both movies are about public bath for men. Lots of humors. Fun watch. Story are different, but it bring some healing, warm, friendship to the overall story
