The Yanqing Dazhuang Branch Liao Dynasty's Mining and Metallurgy Sites are relatively well-preserved Legal Evening News Yesterday, the results of the 2014 National Top Ten New Archaeological Findings were unveiled. The Yanqing Dazhuang Branch of the Liao Dynasty was listed on the Liao Dynasty Mining and Metallurgy Relics Group, and it was dubbed “Beijing Shougang 1,000 years agoâ€. This is another project that Beijing has chosen for another 25 years. The basement of the Ming and Qing dynasties of the Forbidden City was unfortunately lost with a difference of 3 votes. According to Guo Jingning of the Beijing Institute of Cultural Relics, the Dazhuang Section of the Liao Dynasty's mining and metallurgy site consists mainly of mines, smelting, residences, and workshop sites. The distribution areas are mainly in Shuiquangou, Tieluucun, Hanjiachuan, and Shimuchuan. There, it has been discovered that there are 10 relatively complete metallurgical iron smelting furnaces, which are the iron smelting sites that have been preserved in the Liao dynasty iron and steel relics that have been preserved in China for the most part, and whose furnace bodies are relatively well-preserved. Examining the furnace structure disclosed provides valuable information for correctly understanding the evolution of the furnace structure of the ancient iron-smelting blast furnace in China, and Guo Jingning laughed and called it “a good stove for Chinaâ€. "Dazhuang Section is equivalent to the Liao Dynasty's Shougang." In the era when steel was the main tool material, the output of this "steel mill" was staggering. The No. 1 and No. 3 furnaces (round furnaces) in the four blast furnaces can produce 1.2 tons per day. The structure and production of the furnace are also beyond the reach of the small blast furnaces that used to make steel in the 1950s. At that time, the technology was absolutely at the most advanced level in the world. According to Liu Naotao, a staff member of the Beijing Institute of Cultural Relics, judging from the relics of the relics obtained, the weapons of production are mainly weapons. Beijing has been the capital of China since Liaojin, but the remains found in the past were mostly tombs and it is difficult to directly verify the status of the capital. The large and well-preserved “Liao Steel†provided strong evidence. At the same time, in the past five years, the attention of the Chinese archaeological community to the handicraft industry has increased. Especially the attention of the relics of the Song, Liao, Jin and Yuan Periods, which were once unfavorable, began to increase. This is one of the reasons why the “Liao Steel†was selected. At present, this largest site for mineral and metallurgical relics in North China is undergoing conservation planning for large sites. In the future, a site park may be built to facilitate citizens' visits. Forbidden City: Excavation area is short The base building of the Ming and Qing dynasties, with a difference of 3 votes, passed the “Top Tenâ€. Wang Yu, director of the Chinese Archaeological Society, believes that the main reason is that the excavation area is limited and it has just begun. Although not selected, the reporter learned that this is the first time that the complete structure of the Ming and Qing Dynasties palace walls, walls, walls, and water drainage systems have been discovered; for the first time, an early Ming Dynasty palace construction site with a clear definite layout has been discovered; for the first time, the Ming Dynasty was clarified. The construction method of the foundation of the Forbidden City wall; for the first time, the imperial kiln porcelain burial pits and the accumulation of waste materials were found to fill the gaps in the court’s handicraft production system and the imperial porcelain management system. Researcher Wang Guangxuan of the National Palace Museum stated that this was the first archaeological excavation carried out in the Forbidden City, which revealed the Ming and Qing dynasties' floor strata and also discovered various precious cultural relics underground in the Forbidden City. In the Ming and Qing Dynasties, the imperfections of the Imperial Palace such as porcelain and jade were not sent to the outside, and many were buried in the palace. It was also found that the skull was used as a skull piece of the Kybara bowl. According to the regulations, unselected archaeological findings can continue to be excavated next year and continue to stand for election.
