Raising Children for Old Age, a Father's True Ending

Li Dehou only believes in an old saying in his life: raise children to prepare for old age. He had been poor all his life, was hungry, dropped out of school, and killed pigs and sold meat for decades. He raised his three sons, married them wives, and built buildings for them. He thought that he would always have someone to rely on when he got old. But he doesn't know that some sons can't prevent old age even if they are raised. When he was seventy years old, he spent all his savings to build a five-story building in the town. The sons live upstairs, and he and his wife live in the subdivision under the stairs. When his wife was sick, his sons did not give him money for treatment; when his wife left, he lived alone in the dark, and no one came to see him anymore. When he was eighty, he tied a belt around the door frame of his compartment. This is a true story, a true ending of a father.
