Master Cui spent 15 years on the alumina production lines at Weiqiao Group in Shandong province, one of China's largest traditional manufacturing enterprises. He knew every sound the machines made, every vibration that signaled a problem. His hands could diagnose what instruments couldn't measure.
Then the AI systems arrived.
By 2024, the factory faced a stark reality: an aging workforce, production efficiency bottlenecks, and competitive pressure to automate. Under the group's "AI+" strategy, they introduced AI visual quality inspection and intelligent data systems. The result: a production line that once required 200 workers now ran with 20.
For workers like Master Cui, the message was unmistakable — your hands are no longer needed.
But Weiqiao took a different path than most companies. Instead of simply cutting headcount, they launched a comprehensive retraining initiative. Every worker was offered six months of free AI training, partnered with local vocational colleges. The curriculum covered AI operations, digital management, and safety monitoring.
Master Cui, in his 50s, could have resisted. Many workers his age did. But he enrolled in the three-month intensive program.
"The first week was terrifying," he admitted. "I'd spent my whole career with my hands on equipment. Now I was sitting in a classroom learning about data dashboards and algorithm monitoring. I felt like a student again."
The breakthrough came when he realized his domain knowledge wasn't obsolete — it was the foundation. His 15 years of understanding production line anomalies made him better at training the AI quality inspection models than engineers fresh from university who had never seen an alumina plant.
He passed the certification exam and transitioned into the role of intelligent data assistant operations specialist. His job: maintaining the AI systems that replaced his old one, troubleshooting when the models made errors, and serving as the bridge between the production floor's practical knowledge and the algorithms.
His monthly salary went from 4,500 yuan to 6,200 yuan — a 38% increase.
"Before, I only knew how to operate machines," he said. "Now I teach machines how to work. The feeling is completely different. I feel like I started a second career at an age when most people are counting down to retirement."
His story is part of a broader transformation at Weiqiao. Of the workers who faced displacement, 85% successfully transitioned through the retraining program. The factory's production efficiency increased 300%. Workers collectively created over 800 AI applications using a no-code platform, including a hazard identification system that has caught over 800 safety risks.
Not every factory has followed this model. Across China's manufacturing belt, many companies simply cut older workers first, offering no retraining. Master Cui knows he was lucky.
"I tell my coworkers: don't wait for the company to decide your fate. Learn the new tools before they learn how to replace you."
