The letter wrote: "I hope that comrades will vigorously carry forward the fine tradition of patriotic dedication, pioneering and innovation, and hard work, actively practice the concept of green development, increase exploration efforts, strengthen scientific and technological breakthrough, play a greater role in the new round of mineral exploration breakthrough strategic action, and strive to write a new chapter of the 'heroic geological team' in order to ensure national energy and resource security and make new contributions to the comprehensive construction of a socialist modern country." The geologists, represented by Team 6 of Shandong Provincial Bureau of Geology and Mineral Resources, have taken root in the front line for a long time, waded through mountains and rivers, and overcome difficulties, providing indispensable resource guarantee and basic support for national construction. As the "industrial food", energy and mineral resources are the essential material basis for national development, and directly related to the national economy and people's livelihood and national security. Therefore, the geological cause of our country has been closely linked with the fate of the country and the nation since its inception. From Li Siguang, who tried hard to learn and became well used by the country, to Liu Dongsheng, who had a big heart and sincerely served the country; From Daqing oil workers, who are passionate and eager to seize the day, to geological exploration teams in the new era, who are far away from prosperity and are willing to be lonely; Countless geologists have dedicated their knowledge, youth and even life to the mountains and rivers of the motherland. Exploitation and innovation is the action consciousness formed by geologists through unremitting efforts. On this basis, the sixth team of Shandong Bureau of Geology and Mineral Resources continued to tackle key scientific and technological problems in deep exploration, drilling technology and other aspects and achieved fruitful results. It is with this spirit of truth seeking that Chinese geologists devote themselves to research and tirelessly explore new ways to solve geological prospecting problems. Especially since the 18th National Congress of the Communist Party of China, China's geological exploration has made a series of remarkable achievements, which are inseparable from the power of scientific and technological innovation and condense the wisdom and dedication of thousands of geological workers. Hard work is the spiritual background of geologists, which is paved by hard work. Mountains and valleys, the Gobi Desert, and every corner of the motherland have left behind geologists. "The sun blows like ink" has become their true portrayal. Whether you are exploring and mapping in the field or studying theory and technology in the laboratory, you need to endure loneliness, suffering and polishing. Being tempered by nature together with rocks has made geologists particularly hard-working. The vast number of geologists have developed their talents in practice, worked hard in adversity, and built a brilliant geological cause through hard work. At present, the importance of ensuring the security of national energy resources is becoming increasingly prominent. The concept of green development also puts forward higher requirements for geological resources exploration and development. Facing the Times
