In 1988 in Jiangnan Township, Lin Wanqiu replaced her mother as a salesperson at a supply and marketing cooperative. When she first started working, she was confused because she didn't know how to weigh and remember the prices of goods. She was also looked down upon by her colleague Zhao Hongmei. By chance, she discovered that she could "sense" customer needs - stocking up on scarce creams and nylon socks in advance, greatly increasing the supply and marketing cooperative's customer base. Lu Chenzhou, a township entrepreneur who often came to purchase, noticed her specialness and offered to cooperate, using the supply and marketing cooperative channel to promote the township garment factory's ready-made clothes. Lin Wanqiu relied on his ability to improve his performance, slapped Zhao Hongmei in the face, and seized the opportunity in the wave of the times. Together with Lu Chenzhou, he jumped out of the "iron rice bowl" and went from a supply and marketing cooperative to starting a business. In the era of food stamps and bicycles, Lin Wanqiu wrote a love song full of fireworks.
