Проверьте перевод, плиз Ancient China is still unknown territory. Recently, in the course of archaeological excavations in ShanxiProvince in northern China, were found indirect evidence of the existence of an unknown state, which has not yet been mentioned in any source. On bronze ware, which archaeologists have found, engraved the name Ba Bo, who lived in the kingdom of Ba. The time of manufacture of these products are dated XI-VIII centuries BC. In ancient China, then ruled by the Xizhou, but written records of the time do not mention about the kingdom of Ba. Experts suggest that an unknown state was too small and weak to stay in the chronicles. So, apparently, ordered historians of ancient China, not mentioning the kingdom of Ba word. But information about the ancient state of Ba reached our times through the bronzes. Small ancient state managed to convey his "message" to future generations. With these finds we could "learn something new about the feudal system and technology Xizhou Dynasty, as well as trade and unification of different ethnic groups of the period," according to archaeologist Wang Wei of the Chinese Academy of Sciences.

We still have thousands skillfully made copper, jade, gold and bronze subjects testifying to surprising variety of the Chinese civilization. Scientists believe that in front of them waiting for new discoveries, new "message of antiquity."
