Under such a severe situation, geologists Sun Jianchu and others should be hired by the ”Resource Commission“ Preparatory Office of Gansu Oilfield to carry out petroleum geological surveys in the Yumen area. Shortly thereafter, Sun Jianchu confirmed the value of Laojunmiao oilfield production and proposed a drilling program and well location in his article ”Geological Report of Yumen Oilfield, Gansu Province.“ On May 6, 1939 Laojunmiao Well No. 1 drilled in August of that year won the prestigious industrial development of Yumen Oilfield. By the liberation of Yumen in September 1949, the total number of wells drilled was 48, with a total output of nearly 500,000 tons of crude oil. In the book ”Contemporary China’s Oil Industry,“ there is a passage like this: ”On the eve of the liberation of Yumen Oilfield, in order to prevent the Kuomintang troops from entering the oilfield
