As we all know, Chinese civilization has a long history. With the development of history, the culture of our country in various periods has all merged into the long cultural stream of the Chinese nation. Among them, Siwa culture has far-reaching influence. When it comes to Siwa culture, many people must not know it very well. When talking about Siwa culture, we have to first understand a person, Anderson. During the Republic of China, through unremitting efforts, Andersen successively discovered the Zhoukoudian ruins in Beijing, the Yangshao cultural ruins in Henan, the Banshan ruins, and the Qijiaping ruins, etc., which were all extremely important discoveries in Chinese prehistory, and Anderson was praised for this. He is the "Father of Yangshao Culture" in our country. In the 1920s, Anderson was collecting painted pottery in Lanzhou, and he found a worn-out painted pottery jar from a small stall in Lintao County. Later, Andersen was interested in the dilapidated pottery pot. After careful study, he believed that the significance of this cultural relic was far-reaching. Subsequently, with the help of local missionaries, the Siwa Cultural Site, characterized by Ma'ankou plain pottery jars, was discovered in Siwa Mountain, Lintao Yamen. As a typical representative of prehistoric culture in the upper reaches of the Yellow River, the pottery unearthed from the Siwa site is famous throughout the country, and the saddle-shaped jars are the most distinctive pottery. The Siwa cultural site is mainly distributed in Gansu Province east of Lanzhou, and extends to thousands of Shaanxi provinces. In the Shui and Jing River basins, the tombs are mostly made of earth, shaped like buckets, and have coffins or coffins. There are single burials, joint burials and cremation tombs. The funerary objects include pottery, bronzes, decorations and a few bones of cattle, sheep and horses. Martyrs and accompanying chariots and horses were also found in the tombs, which shows that they had entered a slave society at that time. The bronzes at that time included Ge, spears, arrowheads, knives and bells. In 1958, archaeological experts discovered it in Liujia Village, Zhuanglang County. An ancient tomb site was discovered. As the first Siwa cultural site in the Wei River Basin, the discovery of this site attracted great attention from the archaeological community. When archaeological experts were cleaning the tomb site, they unearthed a large number of pottery and bronze vessels, including one. A unique treasure, it is a bell-headed bronze dagger. It is beautifully cast, unique in shape and well-preserved. It was recognized as a national first-class cultural relic in 1996.
