Jinao [2] is Mr. Li Xuezhi, an engineer in Tengzhou; Chairman Mao Zedong/KLOC-visited Shandong in October, 1959, and when he saw many people gathered together to bake pancakes one by one, he said with emotion, "It would be nice to bake pancakes with machines." Relevant leaders in Shandong paid great attention to it and began to develop jinao, but of course, they did not achieve substantial success. Jinao prototype appeared in Tengzhou and Zibo successively, but there was no feasible pancake production method and machine production mode. It was not until 1989 that Mr. Li Xuezhi, a retired cadre with technical background in Tengzhou, resumed trial production in jinao. It was not until 1992 that jinao really formed a complete system from machine production to pancake production method. Machine production was supported by theory, and pancake production had written production methods and principles.
