Chengju Technology Textile Factory Park, Hongan Road, Shi Jia City, Hua Fu, enrolls students all the year round. Without acquaintances, knitting is difficult to learn. Even if you study in a factory, you may not find a job when you come out. The looms in each factory are different, including air-jet looms, water-jet looms, woven fabrics and chemical fibers, and filaments and thick filaments. The machine is made in China and imported. No acquaintance can teach himself in the factory for a year, but acquaintances can do it for three months!
