Death of Zhao: In 229 BC, the State of Qin sent a general, Wang Jian, to attack Zhao. In the first 228 years, Qin Jun entered Handan, and Zhao Wang handed over the map of Handan, and Zhao perished.
At this time, Gong Zijia was king, that is, he established a representative country, continued to linger, and insisted on fighting Qin. Finally, Qin attacked Liaodong and destroyed the generation in one fell swoop. At this time, Cai Zhao was really extinct.
Extended data:
After the three kingdoms were divided into Jin, Zhao, a powerful northern country, was established. Qin people are tough, while Zhao people are brave and determined. Since King Wuling of Zhao was shot on horseback, Zhao has gradually become stronger and won many battles against the northern Hu people (nomads).
The Hu people were impressed by Zhao's bravery, and they admired Zhao very much (during the reign of Emperor Wu of the Han Dynasty, the Huns surrendered to the Han Dynasty and gave them more surnames).
Zhao's national strength is not as good as Qin's, nor is it as dangerous as Qin's astronomy, but its military strength is not inferior. Zhao people have been at war with the Hu people for a long time, and naturally they have developed perseverance and superb fighting skills. They are the most powerful country against Qin among the seven countries.
