Gao Mancang, 58, drifted away from home for five years, returning in a down-and-out, injured state. His eldest son, Gao Jianye, and daughter, Gao Yanmei, seeing him empty-handed, showed utter disdain and made things difficult for him, fearing they would be dragged down. Only his youngest son, Gao Lei, and daughter-in-law, Su He, ignoring gains and losses, meticulously cared for him as he healed, venturing out in the heavy rain at midnight to seek medical help. The old man publicly revealed the truth, measuring sincerity with his family property, rewarding loyalty and kindness, and awakening the snobbish. The family untied their emotional knots and returned to harmony. A test of returning home exhausted the warmth and coldness of rural family affection, proving that sincerity far outweighs a thousand pieces of gold.
