Lin Wanqing and Zhou Chengze worked hard together after marriage to build a small home belonging to the two of them. His parents came to live with them for three years, and family expenses were basically borne by the young couple. The mother-in-law was partial to her daughter, wanting to let the elder sister's family move into the home without discussion, and even wanting to occupy the young couple's master bedroom. Facing the coercion of family affection and moral kidnapping, husband Zhou Chengze held his ground, stood shoulder to shoulder with his wife, clarified family expenses, and drew clear boundaries for getting along. After conflicts and friction, the family learned to respect each other, the elders returned to their own residence, and the young couple guarded their small home, understanding that family affection requires boundaries and equality.
