Fayun Yang, founder of Xinghua Jewelry and member of Dongguan Metal Jewelry Industry Association, began her entrepreneurial journey in debt. For six months without a vehicle, she delivered goods by bus with shopping bags, becoming recognizable to drivers. With no resources, clients, or industry connections, she single-handedly developed the market through door-to-door visits, adopting a make-to-order production model. The couple divided responsibilities - her husband oversaw production while she managed sales and service. Enduring Guangdong's sweltering heat, she often carried samples in one hand and baby bottles in the other on crowded buses, her clothes soaked with sweat and milk stains. While her husband calibrated machines in their 10-square-meter rented room late into the night, she walked home carrying their sleeping child under streetlights, then immediately discussed client revisions. This perseverance earned them repeat customers and stabilized operations, making them treasure every client's feedback all the more.
