Imagine something as thin as 0.003 millimeters, that's nearly one percent of the thickness of a human hair.

It is the machine precision achieved by Liu Zhong, 56, a senior technician at Sichuan Lingfeng Aviation Hydraulic Machinery Co, a subsidiary of the Aviation Industry Corporation of China based in Deyang, Southwest China's Sichuan province.

With 33 years of experience in the field of aircraft precision machining, Liu's work centers around ensuring the smoothness and flatness of aircraft parts, contributing to the advancement of the country's aviation industry.

Born into a family deeply rooted in aviation industry, Liu and his two brothers followed in their father's footsteps. All three joined Lingfeng Company, driven by a shared passion for aviation. Starting as a frontline miller, Liu's expertise shone through when the company introduced computerized numerical control (CNC) technology and equipment in 2000.

Determined to master the new technology, Liu purchased a computer with borrowed money, diligently studying and experimenting, and became one of the first operators of CNC equipment in his company. Over the years, he continued to hone his skills and earned many national and provincial accolades.

In 2016, the Liu Zhong Skilled Master Innovation Studio was established, the first of such group in Liu's company named after an individual employee.

"Since its establishment, the studio has mainly dedicated to tackling technical challenges related to aviation products and solving multiple technological issues. Through technological transformation and innovation, the production processes and efficiency of various products have been significantly improved, with some even increasing by several dozen times," Liu said.

Under his leadership, the studio has expanded from five to 17 members. It now plays an active role in skills transmission, quality inspection, and the application of new technologies.

As a two-term deputy to the National People's Congress (NPC), Liu has integrated his craftsmanship into his duties as a lawmaker. Through meticulous survey and consultation with experts and fellow workers, he has submitted numerous suggestions on issues spanning various areas such as the welfare of technical workers, environmental governance, vocational education, rural vitalization, development of cultural tourism and manufacturing growth.

Liu's dedication to his role extends beyond formal procedures; he actively engages with the community to understand their concerns. Concerned with encounters with elderly individuals facing neglect and health issues, he advocated for improved care for the elderly, showcasing his commitment to addressing societal challenges.

Liu said that serving as an NPC deputy requires the precision and innovation in his technical work. He believes by upholding a rigorous attitude and fostering an innovative spirit, he can fulfill the mission entrusted by the people.
