Shower (1999)

Shenzhen businessman, Da Ming, goes home to Beijing when he thinks his father has died. He finds his father hard at work at the family's bathhouse (the false message was a ruse of Da's mentally-handicapped, exuberant brother, Er Ming, to get Da home). Da stays a couple days, observing his father being social director, marriage counselor, and dispute mediator for his customers and a boon companion to Er. Da is caught between worlds: the decaying district of his childhood and the booming south where he now lives with a wife who's not met his family. When Da realizes his father's health is failing and the district is slated for razing, he must take stock of family and future.
