After the founding of People's Republic of China, through geological exploration and public reporting, it was discovered that China has very rich resources of minerals.
On December 31, 1949, during Chairman Mao Zedong's visit to Russia, he met the Chinese student representative Ren Xiang (任湘), and inscribed on his notebook "Develop the Mines" (开发矿业), expressing China's hope of developing the mining industries. Ren Xiang (1926-), geothermal expert, is also known as the "father of Chinese geothermal".
On December 9,1978, the Ministry of the Posts and Telecommunications of People's Republic of China released a set of four stamps about China's mining industries. The set was named "Develop the Mines", using Chairman Mao's inscription in 1949.
