However, Luo is still concerned about the future. "Looking at the current state of the glass industry, there are fewer young people in the factories," she said.

She's had many opportunities to move away from the front line, and the factory leaders had repeatedly offered her office management positions. "I feel that the furnace and the workshop are my stage," she said.

Luo expressed concern about the inheritance of the craft. The glassware manufacturing process has evolved over several generations, from simple daily-use glass to gifts, crafts and even art pieces.
