What are the flags and slogans of Westernization School in establishing modern military industry and civil industry?

Slogan: learn from foreigners to control foreigners.

The Opium War was mainly divided into four stages:

In the first stage, that is, during the Westernization Movement, they ignored the enlightened landlord class, put forward the slogan of learning from foreigners to control foreigners, and began to develop modern industry and commerce. The main purpose is to raise funds for military enterprises. Many modern industrial and commercial enterprises jointly organized by the government and the people, such as Anqing Ordnance Institute, Fuzhou Shipbuilding Bureau and Hanyang Iron Works, objectively promoted the development of industry and commerce until the Westernization Movement failed in the Sino-Japanese War, and industry and commerce fell into a trough.

In the second stage, during the Reform Movement of 1898, the reformists, represented by the bourgeois reformists, put forward many policies and measures conducive to the development of industry and commerce. Although many of them were not finally implemented, they also contributed to the development of industry and commerce.

In the third stage, after the Revolution of 1911, Sun Yat-sen and others who overthrew the Manchu rule and represented the interests of the bourgeoisie formulated a series of policies to vigorously develop industry and commerce, which developed rapidly during this period. However, with the failure of the Revolution of 1911 and the exploitation and oppression of imperialism, it finally sank again.

In the fourth stage, after the outbreak of World War I, imperialism was too busy with war to look east. The national industrialists headed by Yan Fu and others put forward the slogan of saving the country through industry, and industry and commerce reached their peak in this period. With the end of World War I, the imperialists returned to China, and they soon fell into depression.
