Old Lin, a "tea regular" at the old street teahouse, spends his days doting on his granddaughter Xiaotang, his life as mild as warm tea. Until Xiaotang’s intangible cultural heritage design studio is vandalized by a multinational company—she’s framed for plagiarism, ordered to pay three million yuan, or be blacklisted from the industry. When Xiaotang bursts into tears in Lin’s arms, clutching her torn design drafts, the old man pulls out a "WIPO Intellectual Property Advisor" certificate he’s kept for thirty years—this "good old man" who fixes pipes for neighbors was once a legendary "IP Living Dictionary" in the 1980s, able to turn the tide of international patent battles with just a pen. Soon, Old Lin’s figure poring over documents with reading glasses becomes a nightmare for the opposing legal team, and Xiaotang learns that Lin retired to care for his terminally ill daughter (her mom), and now, for her, he’s willing to "come out of retirement."
