Eight sophomores of Harbin Normal University, majoring in conservation technology were having field practice, they found an incomplete bronze ware with emblazonry, a scrape opal flag and many pottery shards in Tianheng Mountain of Harbin, Daowai, Tuanji town. Researchers from the Harbin Cultural Relic Management Station identified that the site the relics had been discovered on dates back over  two thousand years to the early Western Zhou Dynasty to the late Western Han Dynasty. History experts say that bronze ware is the significant symbol that a space enters into an age of civilization. This bronze ware with emblazonry offers a new argument for the beginning of an era of Harbin City. The origin of Harbin City perhaps now can be dated as far back as two or three thousand years ago.
