In 1960, there was a natural disaster and food shortage, and everyone lived on tickets. Lin Xiu'e dressed up as a female worker in a state-owned factory. She lived in a tube building with bare walls and counted food stamps at the end of the month. The "Buy Buy Buy Purchasing Group" popped up in her mind. Answering questions and solving problems can be exchanged for points, which can be exchanged for rice, flour, grains, oils, fabrics and medicinal materials. Low-key exchange, hidden under the bed, hidden for home use. Relatives were squandering food and colleagues were jealous, so she borrowed money from the supply and marketing cooperative and used clever words to deal with it. With a golden finger in hand, she kept her family fed and clothed, and quietly hoarded goods to make a fortune. No CP, focus on career, counterattack and become the richest family in Tongzilou.
