Sunken relics More than 10,000 cultural relics that sank to the bottom of the Minjiang River nearly 400 years ago have been found in Pengshan District of Meishan, Sichuan Province, since an archaeological* dig started in early January. The items include gold, silver and bronze coins, jewelry, iron swords, spears*, rings, earrings and hairpins. They provide proof that the river is where Zhang Xianzhong fought against a local general in 1646 and left countless treasures in his sunken boats, according to the Sichuan Provincial Cultural Relics and Archaeology Research Institute.
