Zang Lanlan, Director of the Car Body Office of the Urban Railway Development Department of CRRC Dalian Locomotive and Rolling Stock Co., Ltd., a professor-level senior engineer, a Chinese labor model, the winner of the China May 1st Women's Medal, and a representative of the 13th Dalian Party Congress.

China is the country with the fastest development of urban rail transit and the longest total operating mileage in the world. The independent research and development of China's urban rail vehicles has also grown from scratch, from weak to strong, and is entering a leap stage of rapid upgrade. Zang Lanlan, who has been deeply involved in this field for more than 20 years, is a participant and witness of this great era.

Zang Lanlan and her colleagues worked hard and worked hard, and achieved "zero breakthroughs" time and time again. Since the successful rollout of the company's first urban rail vehicle in 2002, she has led the team and presided over the completion of the R&D and design of more than ten types of rail transit vehicle bodies; all the company's domestic and foreign urban rail vehicle orders and R&D projects have been Hosted by Zang Lanlan and participated in the design.

Zang Lanlan believes that only continuous innovation and research and development of core technologies with independent intellectual property rights can support the "steel and iron bones" of urban rail vehicles.Editor/Ma Xue
