Warring States In the early third century BCE, the
state of Chu sent Zhuang Qiao to Yelang at the head of a military expedition to prevent the state of Qin from annexing these kingdoms. After negotiating these alliances with the state of Ba, who helped Zhuang Qiao negotiate passage through the state of Bi to reach Yelang. Yelang also accepted the terms of the agreement and Zhuang Qiao went further west to the Lake Dian region. However, in 281 BCE the
Qin state sent Sima Cuo to intercept this threat to its interests and attacked Ba, eventually persuading Ba, Bi and Yelang to switch to alliances with the Qin.
Nanyue Yelang had a close relationship with the
Nanyue ("Southern Yue") kingdom and used the
Zangke River (now known as the
Beipan River) as a means of international transportation. The kingdom of Yelang declared their allegiance to Nanyue rule from the start of 183 BC until the end of 111 BC. The
Yi people may be modern-day descendants of the Yelang kingdom. ==In Chinese culture==
