Starting with 200,000 yuan in the stock market, Niu San makes a spectacular comeback and builds a fortune worth tens of millions. Riding high on his success, he takes on leveraged investments, manages other people's portfolios, and cultivates influential connections over lavish dinners, convinced he was born to be a stock market genius. But when the market suddenly turns, his positions are liquidated and his fortune wiped out. He sells his home to repay his debts, his wife and child leave him, and those who once showered him with praise disappear overnight. At rock bottom, he starts over from scratch, working in a factory and running sales orders. After twelve years of ups and downs in the stock market, he finally realizes: "Fame and fortune in the stock market are nothing but illusions. What truly matters is taking good care of your family."
