Rent Family Nest (1979)

In a one-room apartment, live a man, his wife and two children - along with his grown son and his wife and child - a total of seven people in one tiny space. On returning from a tour of duty in the military, the grown son is scolded by his father for not reenlisting, which might have enabled them all to qualify for a larger apartment. The drive to have more space leads the older man's wife to spend time with other men in order to somehow qualify for another apartment. When the older man refuses to give his wife the money to bribe a housing official, she angrily leaves, taking her daughter with her.
