193 1 year (20 years of the Republic of China), Liu Weishi was forced to move to Xi 'an to make a living. During his stay in Angola, he carved stones for a living, then converted a gasoline stove into a desktop steam lamp and gave it to General Yang Hucheng, then director of Shaanxi appeasement office. General Yang liked it very much, so Liu Weishi was able to use the machine tools of Yangbu Ordnance Institute to carry out scientific and technological research and invention, and made the first small-scale alcohol making machine, which used corn and sorghum as raw materials to produce alcohol and supplied vehicles as fuel. Not long after he was in Ann, Liu Weishi met his alumnus Mr. Yang Cun (Tianshui native, then supervisor of the Central Supervision Institute of the National Government). Yang Cun is deeply gratified by some of Liu Weishi's invention drawings. 1935, personally took him to Nanjing to meet Mr. Yu Youren (then president of the Central Supervision Institute of the National Government). Yu Xiansheng also attached great importance to Liu Weishi's inventions, and personally wrote a letter of recommendation recommending Liu Weishi to apply to the Ministry of Industry of the National Government for his own inventions. Soon, Mr. Yu Youren went to Shanghai to inspect Shanghai's industry and commerce, and took Liu Weishi with him. Mr. Yu Youren specially introduced Liu Weishi's invention at the banquet hosted by the famous Yu family in Shanghai, and strongly recommended it. I hope the participants will help Liu Weishi. After the banquet, Yu Youren organized a press conference to introduce Liu Weishi and his electric fan drawings. Liu Weishi and Yu Youren became the focus of major newspapers in Shanghai. On the front page of Shanghai Ta Kung Pao, the news that the Dean gave a banquet to introduce the invention and creation of Gansu inventor Liu Weishi was published. The title of People's Daily is: Oriental Edison-Liu Weishi and his rotating three-action electric fan. It is said that the rotating three-action electric fan is the first in the world, and its creator Liu Weishi is the first in China. In fact, it is the backup Edison of the East. Even so, due to the current political corruption, Liu Weishi has done nothing in Shanghai. Depressed, in desperation, he took his only remaining antique wine jue (used by General Han and unearthed in Chengxian County, Gansu Province) to Shanghai foreign "Decroo Mo" factory in exchange for an old universal machine tool, which was shipped back to Nanjing for installation, and then continued the research and trial production of electric fans. After more than a year of experimental research, the three-action electric fan and the loose-leaf electric fan were successfully trial-produced. In Nanjing, he carefully carved a seal with the words "Shao Lizi" on the front, Chimonanthus praecox in bud on the front wall, and the full text of "Red Cliff Fu" on the back wall. Shao Lizi couldn't put it down after seeing this seal. When he said that Liu Weishi was studying electric fans, but he didn't have the money to make them in kind, he generously helped 1500 yuan and solved his difficulties. With the support of Mr. Shao Lizi, Liu Weishi began to trial-produce electric fans.

At that time, Nanjing Pioneer Magazine published the invention of "three-action electric fan" and Liu Weishi. He also commented on the topic of "Congratulations to Liu Weishi and Thanks to Shao Lizi", saying that it is not easy to invent, and it is even more difficult to wait for the invention funds. As far as the invention of rotating three-action electric fan and ceiling electric fan is concerned, it would only be a plan if it were not for Mr. Shao Lizi's generosity 1500 yuan! Therefore, the success of the invention of electric fans is largely attributed to Xiao's strength. When the social economy was depressed and everyone regarded money as their life, Shao was able to generously fund the invention and make Liu's plan come true. That's not really good for mankind! Besides congratulating Liu, we can't help thanking Xiao! ? Liu Weishi is a native of Gansu (Jiangsu). He once graduated from Gansu University of Political Science and Law, and there was no scientific culture to rely on in his environment. You can imagine. Because I have been engaged in the invention work without the guidance of any scientist or engineer, I can only grope in secret and have achieved great success. However, 19 (9 out of 10) young people with years of scientific training and rich qualifications have not achieved anything. It can be seen that the success of the invention lies not in objective reference, but in subjective efforts. Young people have this example and work hard! Sure enough, a large number of inventions emerged. After more than ten years, China has a way of everything. How can it be poor and weak? May young people encourage each other.
