Later, it was found that the king of Qin really did not have the sincerity to exchange, so he took the jade to force him to die and asked the state of Qin to give way to the city first. the king of Qin consciously agreed to give the city back to the temple. Lin xiangru sent him back to Zhao overnight, which is known as the story of returning the jade to Zhao.
