But they were not powerful enough. Threat did exist among the states and the threat was also from the northern ethnic minorities. One day, the Latter Zhou heard that Northern Han and Qidan people wanted to fight against their country. Then, the general Zhao Kuangyin was asked to defend. On the way, Zhao Kuangyin's subordinates said the emperor of Latter Zhou was too young to dominate the country and they hoped Zhao was crowned. Zhao pretended to be unwilling to accept this request. At this moment, his brother put the emperor's robe on his back and declared Zhao was the emperor.
