What spirit is symbolized by three old men and four strictnesses?

When dealing with the revolutionary cause, we must be honest people, speak the truth, and do honest things; when dealing with work, we must have strict requirements, strict organization, serious attitude, and strict discipline.

The term "Three Elders and Four Stricts" first appeared in 1962 and became a complete expression in 1963.

"Three Laos and Four Stricts" is the style formed by Daqing Petroleum employees in battle practice.

The background of the formation of the Three Laos and Four Stricts: In the early 1960s, in order to completely get rid of China's oil-poor label, more than 50,000 elite soldiers in the national petroleum system gathered in the Songliao Basin with the ambition of dedicating oil to the motherland, and launched a magnificent campaign.

The Petroleum Conference made an outstanding contribution to the development of New China's petroleum industry that will shine in the annals of history.

In the historical process of the development of the petroleum industry, a large number of advanced models represented by Wang Jinxi emerged, creating the great Daqing spirit and the iron man spirit, and forming the fine traditions and styles of three Laos, four stricts and four strictnesses.
