过去学术界认为楚文化西界止于巴东,巴楚交界于巫山。然近年来峡江地区所发掘出的楚文化遗存却显示楚人在战国中期已到达云阳、忠县等地,生动地再现了东周时期巴楚关系的变化。二者之间关系的变化,是由政治目的和经济利益决定的。 Academics in the past thought that the western boundary of Chu Culture ended in Badong, Bachu border in Wushan. However, the Chu cultural relics unearthed in the Xiajiang River area in recent years show that the Chu people arrived in Yunyang and Zhongxian in the mid-Warring States period and vividly reproduced the changes in the Bachu relationship during the Eastern Zhou Dynasty. The change in the relationship between the two is determined by political goals and economic interests.
