Tianshui is believed to be the birth place of Fu Xi, one of legendary ancestors of the chinese nation. According to some experts, the biggest invention he made for his people was the eight divinatory symbols, which was the earliest written characters. It is recorded that Fu Xi was the first to teach people how to catch fish with nets, and how to cook food, grind grain and make clothes. (Xinhua/Guo Gang)
