Jinzhong has a long history and outstanding people. Jinzhong is one of the birthplaces of the Chinese nation. Since the primitive society, human activities have appeared here. According to research, the history of Jinzhong can be traced back to the late Paleolithic period, about 30,000 years ago. In the late Shang Dynasty, cities appeared in China, and the county-level administrative system was established in the Spring and Autumn Period. After Qin and Han Dynasties, most counties in the city were generally established. In ancient times, Gong Yu was divided into nine continents, with Jinzhong as Jizhou territory, the Western Zhou as Bingzhou, the Spring and Autumn Period as Jin Dynasty and the Warring States Period as Zhao Dynasty. After the Qin and Han Dynasties, most of them belonged to Taiyuan County. During the Sui and Tang Dynasties, except Yushe and Lingshi, it was still under the old system, which was under the jurisdiction of Taiyuan in the late Qing Dynasty and Jining Road in the Republic of China. During the Anti-Japanese War, Jinzhong belonged to three anti-Japanese border governments: Shanxi-Hebei-Shandong-Henan, Shanxi-Chaji and Shanxi-Sui. During the War of Liberation, Jinzhong was subordinate to the administrative offices of Taihang, Taiyue and Shanxi-Chaji. After the establishment of People's Republic of China (PRC), Yuci District was set up to administer 13 county and Yangquan industrial and mining area. Later, in the 1950s, 1960s and 1970s, the urban administrative divisions were adjusted three times, from June 1983 to June 10, and Jinzhong governed 10 counties and 1 city. 65438+1 September, 1999, land was withdrawn to set up a city, which governs 9 counties, 1 district,1city and Yuci Economic and Technological Development Zone. A long history has given birth to a splendid culture of Shanxi merchants. In the middle of the Qing Dynasty, Shanxi merchants, represented by "Shanxi banks are all over the world" and "national finance is the best", once created the economic miracle of "the richest man on the sea".

Jinzhong has rich agricultural background and rapid agricultural development. Jinzhong is one of the ancient birthplaces of agriculture in the Yellow River Basin. As early as Yangshao culture period, it has entered the farming stage from slash-and-burn primitive agriculture. Agriculture dominated during the Spring and Autumn Period and the Warring States Period, and intensive cultivation gradually formed during the Sui, Tang, Song and Yuan Dynasties. In the late Qing Dynasty, Ma Shou Nong Yan, written by Qi Juanzao, a generation of college students who lived in official positions, played an important role in Shanxi's agricultural history. It is in this land with profound farming culture that the industrious and intelligent children of Jinzhong worked tirelessly to create the agricultural glory of Jinzhong. Since the reform and opening up, especially since the Ninth Five-Year Plan, the Jinzhong Municipal Party Committee and Municipal Government has taken the lead in implementing agricultural industrialization, especially in the face of the new challenges of agricultural development entering a new stage and China's accession to the WTO, and has made every effort to promote the strategic adjustment of agricultural industrial structure, and has carefully constructed the "two districts and three belts" advantageous industrial pattern of four major industries: traditional high-quality coarse cereals, special dried and fresh fruits, timely pollution-free vegetables and green livestock and poultry products. Efforts have been made to build a large number of famous brand bases in Pingyao, the hometown of beef, Taigu, the hometown of walnuts, Zuo Quan, Yushe and Shouyang, which are famous in the whole province and even the whole country.
