Soon after he became self-reliant, he wanted to send troops to crusade against the post-Qin Dynasty, but at that time, all the generals were opposed to sending troops to the post-Qin Dynasty, and suggested that he should stick to Gaoping and stabilize the foundation first, and then seek Chang 'an. However, it is believed that Xia Guo was built at the beginning of the country, but its strength is still weak. Guanzhong has been unable to capture this place because of the strength of the late Qin Dynasty. If it holds its own city, it will inevitably lead to the joint attack of the towns of the late Qin Dynasty, which will eventually lead to the defeat and national subjugation. Therefore, it is specially not long to live in one place, using guerrilla tactics to surprise the other side, so as to seize the land of Lingbing and Hedong, and then capture Chang 'an after the death of Yao Xing, the monarch of the late Qin Dynasty. These aspects are enough to show Helian Bobo's military talents, and perhaps it is this that has made him unified and founded the country.
in the year 413, after he became the King of Heaven, he was granted an amnesty in China and changed his year name to Fengxiang. He appointed Chigan Ali as a master, and later recruited 1, Hu people and Han people in the north of Lingling, and built a capital in the north of Shuofang and the south of Heishui. The capital was named "Tongwan City". Helian Bobo himself said: "I am about to unify the world and rule all nations. I can use Tongwan as my name."
