From the 9th century BC, two northern Yue tribes on the southeastern coastline of China, the Gouwu and Yuyue, came under the cultural influence of their northern Chinese neighbours. These two peoples were based in the areas of what is now southern Jiangsu and northern Zhejiang, respectively. Traditional accounts attribute the cultural exchange to Taibo, a Zhou dynasty prince who had self-exiled to the south. During the Spring and Autumn period, the Gouwu founded the state of Wu and the Yuyue the state of Yue. The Wu and Yue peoples hated each other and had an intense rivalry but were indistinguishable from each other to the other Chinese states. It's suggested in some sources that their distinctive appearance made them victims of discrimination abroad.
