Liu Dongshan was originally an electrical assistant engineer at the Jingmen Beverage Factory. After being laid off, he found that the car shock absorbers are expensive and have a short life. Once they are broken, they can only be replaced with new ones and cannot be disassembled and repaired. After six years of trial and error, he finally solved this problem and filled the gap in the repair of domestic vehicle shock absorbers.
