What is "learning Daqing and learning Dazhai"?

At the end of 1963, after more than three years' hard struggle, the working class on the oil front in China developed Daqing Oilfield through their own efforts, ending the era when people in China lived on foreign oil, cultivating and training an oil industry team with certain technical quality, organizational discipline and hard work, and emerging an advanced model like "Iron Man" Wang Jinxi. The Ministry of Petroleum summarized the experience of Daqing petroleum battle from nine aspects. 1964 On February 5th, the Central Committee issued a notice calling on other departments in China to learn from the experience of Daqing Oilfield. Since then, the national industrial transportation front has set off a movement to learn from Daqing's experience, and Daqing has also become a banner of China's industrial front. Since then, the slogan of "learning from industry" has spread all over the country.

"Dazhai of agricultural science"

Dazhai is a brigade of Dazhai Commune in Xiyang County, Shanxi Province. This used to be a poor mountain village. After the transformation of the cooperative, the members cut mountains and slopes to build terraces, which increased the grain yield per mu by seven times. 1964 February 10, People's Daily published the communication report "The Road to Dazhai" by Xinhua News Agency reporters to introduce their advanced deeds. He also published an editorial "A Good Example of Building Mountainous Areas with Revolutionary Spirit", calling on the people of the whole country, especially the agricultural front, to learn from the revolutionary spirit of the people of Dazhai. Since then, the "Agricultural Dazhai" movement has sprung up in rural areas all over the country, and Dazhai has become a shining example of China's agricultural front. The slogan of "learning from agriculture" spread to the end of 1970s, and was also used by extreme "left" thoughts.
