On April 19, 1996, Li Junhai, a chemistry teacher at Laiwu Teachers’ School in Shandong Province, was a great joy. He invented the “Multifunctional Chemistry Experiment Stand” and was officially granted a national patent. This was his achievement in teaching and research education reform. Another breakthrough, marking his education and teaching reform work once again been fully affirmed by the community. In 1975, Li Junhai graduated from high school, as a private teacher, began the “high school graduation to teach high school life.” Three years of civilian life, so that he really tasted the “study of useless theory” brought the pain. In order to teach chemistry class, he had to borrow books to chew, go
