Horses are alike
Ma Jun, also spelled Deheng, was a native of the State of Wei, born in Fufeng (in present-day Linyou and Qianxian, Shaanxi) and died in an unknown year. He is one of the most prestigious mechanical inventors in the history of ancient Chinese science and technology. When he was a teenager, he lived in poverty and had the problem of stuttering himself, so he was not good at talking but was good at ingenuity, and later held an official position in the State of Wei. At that time, the textile machine was inefficient, and it took dozens of days to weave a horse. Ma Jun simplified the mechanical structure of the aya machine, and transformed the old silk silk machine of fifty comprehensive (heald piece) fifty traverse (tread) and 60 hydra into 12 tiles, which increased the production efficiency by four or five times. Ma Jun's most prominent performance is the reduction of the guide car, Ma Jun also invented a keel water wheel from the low to the high ground to divert water, the structure is ingenious, light and flexible, the efficiency is very high, is the advanced production tool at that time, long-term widely used in rural China. He also added the hundred plays plus the prime mover and transmission machinery to become a water to play. He tried to produce a rotary stone-blower that can shoot hundreds of steps away (one step is about 1.45 meters). He also improved zhuge crossbows. Contributed to scientific development and technological progress. Famous mechanical manufacturer and inventor during the Three Kingdoms period.
Major achievements: Inventing the guide car, manufacturing the keel tipper, improving the weaving machine, and making the water turn map.
