It's not something like the ranking of Human Demons with Zheng Old Third or Li Old Fourth, but a real blood relationship.
They were born of the same mother, connected by blood.
Their father was a scholar in his youth, but he wasn't good at studying and was expelled after a few years. He turned to business, but everything he did lost money. Later, he became addicted to gambling, losing the family fortune.
Every day he lay on the gambling table, and when he left it, he soaked himself in wine.
Their mother would often leave them uncared for, having affairs outside.
Their father's family had a strong clan influence locally. After their mother's affair was exposed, her lover was drowned in a pig cage.
Because both he and Li Shou were still young and needed care, their mother survived.
The clan needed people, and their father also opened his mouth to forgive.
