Retired teacher Su Wanqing scavenged for old items at a recycling station day in and day out for twenty years, while her husband Shen Changshan and mother-in-law Pan Yulan viewed her as doing proper work not, mocking her endlessly. Their son Shen Xingye's metaverse company went bankrupt, the bridge loan guaranteed by Shen Changshan exploded, and the family bore tens of millions in massive debts, with their property facing auction. At the critical moment, Su Wanqing took out a Ming Dynasty Xuande censer, Hainan huanghuali large timber, and a residual scroll of Song Dynasty Lu You's Ci poetry treasured in her storage room, which were appraised as rare treasures by Shenzhen Museum experts.
