In the past, Wenzhou people had a catchy saying about doing business: Make big money in wholesale, make small money in retail. Familiar customers rely on prices, newcomers rely on service. Men sell women's clothing, women sell men's clothing. In summer, sell cold drinks; in winter, sell cooked food. Open big stores in small towns, open small stores in big cities. At construction sites, open foot baths; in the food industry, gather together. Auto repair shops should be exclusive; pharmacies should stay open until midnight. Milk should be delivered in cups; open a hotel near the university. Pharmacies near hospitals; hardware stores at residential community entrances. Toy stores at park entrances; car wash shops at intersections. Use black bags to sell fish, green bags to sell vegetables, red bags to sell meat. Smile three parts when seeing people, customers can't run away. Be enthusiastic to everyone, and business will definitely succeed. Finally, no matter how poor, refuse to work for others; no matter how hungry, refuse to eat rice prepared by others. Better to sleep on the floor than be a boss, a big boss.
