On February 1st, at the world's first "smart zero carbon" port in Tianjin Port, nearly a hundred unmanned artificial intelligence transportation robots showed their skills here. They carried more than ten meters of containers back and forth, accurately and quickly reaching the automated quay bridge and lifting the containers onto the ship. The huge container terminal is empty, but the loading and unloading site is tense and orderly, bustling with excitement, which is breathtaking. Although these massive transport robots have been on duty in this enclosed area for over two years, their master Cheng Weidong is still not quite at ease. In January 2024, Tianjin Port officially put into use a new generation of intelligent container terminal control system, and Cheng Weidong closely monitored the operation of the control system. On that day, Cheng Weidong was on the observation corridor next to the unmanned smart dock, paying attention to the performance of his disciples. In 1998, after graduating from Tianjin Port Water Transport Technical School, Cheng Weidong came to work at Tianjin Port as a trailer driver, "Learning the best technology, being the best driver, and being the best employee." This is the motto I have set for myself since I started working. "Cheng Weidong told reporters. In order to fulfill his promise, Cheng Weidong honed his driving skills by breaking down one cycle of trailer operation into more than forty action elements and studying them one by one. With the improvement of knowledge and skills, Cheng Weidong is able to proficiently control various advanced equipment and has won the championship of the towing group in the Tianjin Port Industry Vocational Skills Competition for three consecutive times, becoming the youngest senior technician in Tianjin Port and being known as the undisputed "towing king" of Tianjin Port. In addition to striving for excellence in his work, Cheng Weidong also leads his colleagues to constantly learn and innovate. It is understood that every year, he conducts more than 60 skill training sessions for all employees, conducts nearly 40 discussions and technical competitions, and trains more than 200 technical talents. In the Tianjin Port "Kong Xiangrui Cup" Skills Competition, his apprentice won all the awards in the towing group for three consecutive times (top six). He led the studio team to cultivate employees who continuously won championships in various professions such as cranes, forklifts, and maintenance, and more than 20 people won awards. Over the past 26 years of work, Cheng Weidong has driven a 20 meter long and 3 meter wide trailer in a loop between the dock and cargo yard, driving a total of over 300000 kilometers. Years of hard work and impressive achievements have won Cheng Weidong many honors, such as National model worker, National Model of Civilized Workers in the Transportation Industry, "Chinese Quality Craftsman", "The Most Beautiful Port and Shipping Man", etc; In 2023, Cheng Weidong was elected as a delegate to the 14th National People's Congress. In the honor room of Master Cheng Weidong Studio, there are various national and provincial trophies and certificates obtained by Cheng Weidong and his team. Among them, a job offer letter is prominently displayed. This is the appointment letter for "AI Trainer" issued by Tianjin Port to Cheng Weidong. It is also one of his most valued honors. "This is not only Tianjin Port's recognition of my work, but also a witness to my technological upgrading and transformation as an industrial worker in my work," explained Cheng Weidong.
