Where did the bronze civilization in Thailand come from? Is it self-development? Or absorb the technology of other civilizations? According to some scholars' research, the ancestors of Thais were in China. For example, in the book Thai: China's Brothers written by American missionary Turot in the early 20th century, according to the reason that many Thai speakers were seen in China, the Thai people used to be the masters of China. On this basis, another American further concluded that the birthplace of Thais is in the Altai Mountains and the deep areas of Mongolia. Kanchana Pan Ke, a Thai historian, agrees with this view, and formally put forward the view that "Thais originated from Altai Mountain" in the Outline of Thailand. Some scholars disagree that it originated in Altai Mountain. They believe that Thais originated in the southwest of China. An Introduction to Asian Countries, published before the liberation of China, quoted the speech of the King of Thailand in China and the contents of the history textbook issued by the Ministry of Education of Thailand. The King of Thailand once said, "Not only am I of China descent, but 67% of my subjects are of China descent." . Chinese scholar Lv Meizhen proved that Thai language originated in southwest China from the linguistic point of view, and thought that Thai language was the same as Dai language and Zhuang language in China in terms of genesis and typology. Specifically, the three words have 500 * * * roots, and their pronunciation and grammar are basically the same. If it is not the same origin, it is impossible to have many identical basic words. He also found hundreds of words similar to or corresponding to Chinese from Thai through research, and thought that this close relationship with Chinese and Sino-Tibetan showed that Thai people had the same life or close contacts with * * * in history. Since scholars have fully demonstrated that Thais originated from China, it is natural that China's bronze craft spread to Thailand. Where did the bronze civilization in Thailand come from? Is it self-development? Or absorb the technology of other civilizations? However, there are loopholes in this view, because some scholars have put forward different views on the origin of Thais in China. They believe that Thais have never come from the same race and descent, but there are many tribes as a whole. Therefore, judging by ethnic relations, clan lineage and other factors is totally futile. Today's Thais are' sons of the earth' born by the combination of foreign immigrants and local residents in the long historical evolution process. "Therefore, if the statement about whether Thai people originated in China has not been confirmed, there is no basis for the statement that Thai bronzes originated in China. Where did the bronze civilization in Thailand come from? Is it independently developed, or has it absorbed the technology of other civilizations? Today, there is still a heated debate between those scholars who believe that the bronze civilization of Manchu can be traced back to 3600 BC and those who only admit that it was not earlier than 750 BC, and both sides hold their own words. Some scholars take the middle road, trying to find another way to calm the debate, and put forward the view that Thai bronze craft is neither the earliest nor spread from other civilized areas. It is based on the fact that pottery similar to Man Qing (4000 BC-3500 BC) was unearthed in other parts of Thailand, but no early bronzes were found. The author points out that the bronze civilization in Man Qing may be confined to the Awa Plateau in the northeast of Thailand, because this area is rich in copper and tin, which are necessary for bronze smelting. Due to the barrier of mountains and forests, Man Qing is isolated from China culture and southern Man Qing culture, where smelters can start this process independently. However, few people are convinced of this compromise view, because no civilization in history can develop so independently without being influenced by other civilizations at all. Why does a small bronze spearhead cause such a big debate? Because it is not only the age that is controversial, this discovery seems to rewrite the history books. For example, most of the world history written in the past assumed that all the important historical stages of human development began in a certain region and then expanded outward through trade, war and other channels, just like throwing a stone into a pool, causing many ripples. From this perspective, Mesopotamian culture spread eastward to India and westward to Europe, and clues can be found through generations. China's ancient inventions can also be explored in the same way: they spread westward to Central Asia, southward to Southeast Asia and eastward to Korea and Japan. If the bronze spear unearthed in Man Qing can really be traced back to 3600 BC, it will break the historical pattern of spreading outwards, thus becoming another stone thrown into the water. Will the Thai bronze spear become a stone thrown into the pool and rewrite history? It is believed that with the continuation of excavation work, the discovery of more cultural relics and the deepening of research work, the mystery of Thai bronze spearhead will be revealed to the world.
