Zhao Jianzhong, a senior technician of grade eight who has worked for thirty years, handed all his salary to his wife Wu Guilan, keeping only three hundred yuan a month. On his birthday, he used the remaining money from buying snacks for his grandson to buy a lottery ticket, which was torn up and humiliated by his wife in public. He proposed divorce and resignation, leaving with an old suitcase, unaware that the remaining half of the lottery ticket won fifty million. Wu Guilan's family searched frantically, even making a scene at the orphanage. Accompanied by Director Lin Xiaoyue and the children, Zhao Jianzhong decided to live for himself.
