Cao Sanxi is the key turning point of Cao family from farmers to a generation of rich. Dissatisfied with the present situation, he went to Santa Village (now Liaoyang County, Liaoning Province) in the former Rehe Province of Northeast China. He grows vegetables, raises pigs and lives in grinding bean curd. At first, his life was very difficult. After the business was booming, because Cao Sanxi was a foreigner, the partners wanted to get more profits and had to operate separately. Cao Sanxi believes that his name has the word "three" and he will succeed in the "Three Towers".

He is diligent and practical, treats people sincerely, and his business is getting better and better. With a little savings, he began to make use of the local sorghum, and the brewing industry became the first industry in Cao Jia's development. After Cao Sanxi got the money, he didn't lead a luxurious life, but devoted himself to the development of other industries, which is to expand reproduction in our modern words. So his business soon developed into a grocery business and a pawn business. With the prosperity of the local area, the population of Santa Village is increasing day by day, and the government has established the Chaoyang county system here. Up to now, there is still a saying circulating in the local area: Caojiadian comes first, then Chaoyang County.

Cao Shi family's business intention expanded from Chaoyang to Shenyang, Siping, Jinzhou, Japan and other places, and finally established a strong business foundation in Northeast China in the late Ming Dynasty. 1664, when the Qing soldiers entered the pass, the Cao Shi family began to develop from outside the pass to inside the pass. First, I returned to Taigu to set up a number, and radiated to major cities in the Central Plains with Taigu as the center, occupying more than half of China. Not only that, they also went abroad and went to the world, as far away as Tokyo, Japan, Pyongyang, Russia, Irkutsk, Qiketu, Mongolia and Ulaanbaatar, as far away as Berlin, Germany and France. Spanning Europe and Asia and Wan Li has created immortal glory not only in the business history of Shanxi people, but also in the business history of China people. During the reign of Qing Daoguang and Xianfeng, Cao Shi enterprises reached their peak, with more than 640 firms, assets as high as 65438+ 1 100 million taels of silver and a total of 37000 employees. Cao Jia created the chain management method of managing semicolons and small semicolons. Without the consent of the Cao family, some profiteers borrowed money to open businesses under the banner of the Cao family. As long as it is under the jurisdiction of their banks and banks, the Cao family doesn't ask why, which shows that the Cao family is rich.

After Cao Sanxi became rich, he divided his assets into seven parts and gave one to each son. Then each family invested 654.38 million yuan to form the management office, which was called "Cao Qihe". After Daoguang, the philosophers gradually declined, but Sanduotang flourished. "Sanduotang" means more happiness, longer life and more men. In the west village in the northwest of Taigu City, three towering four-story old buildings stand side by side, which is the symbol of "Three Duotang". The wall thickness of these three buildings is 1.5m, and the height exceeds 15m. The layout of these three halls is in the shape of "longevity", with 15 courtyards and 280 houses, with a total area of more than 6,000 square meters. It is also a famous courtyard of Shanxi merchants. Cao Shi's commerce declined gradually in the late Qing Dynasty. After the Revolution of 1911, Cao Shi's banks in major cities in Northeast China were operated by "tender tickets" issued by warlords. 193 1 After the September 18th Incident, Cao Shi's ticket office in the northeast was owned by the puppet Manchukuo government.

Cao Sanxi is rich because he "controls power by profit" and puts profit first. As long as he can make a small profit, he will do business regardless of size. His management methods are: circular economy, grasping business opportunities, knowing people and being good at their duties, and honesty first.
