Who does the "Dragon City Flying General" in "But the Dragon City Flying General" refer to?

1. General place names: Place names specifically point to the place where they went. Li Guang was born in Longcheng, that is, Li Guang’s name is Flying General. First of all, there is no problem with the number. Wei Qing has nothing to do with it. 2. Wang Changling joined the army in Chengji, that is, he sighed when he came to Li Guang's hometown. The background has nothing to do with Wei Qing. 3. Wei Qing did not reach Shan Yu Wangting: Longcheng in Mobei. He arrived at Congcheng in Monan. The two were thousands of kilometers apart, so the assault was completely meaningless. 4. When you speak, you must provide evidence. Don’t just say that Longcheng refers to Wei Qing and Longcheng refers to Wei Qing. Don’t yell, otherwise you will lose your mind. The name Flying General has been recorded many times in history and refers to Li Guang, while Longcheng refers to Wei Qing, which has never been mentioned in historical materials. 5. Literary records. In the Tang Dynasty, Longcheng and Li Guang were used together, which was a fixed usage. And like Yinshan Mountain, they both represent the border of the Han Dynasty. Wang Changling's "Two Songs on the Military March": The autumn grass is light and the horses' hooves are light, but the horns and bows are holding the strings urgently. We went to fight for Dragon City when Hu soldiers were attacking (this trip was to fight for Dragon City, and Dragon City was being attacked by Hu soldiers. This shows that Dragon City belongs to the Han, not the Huns.

If here It's not obvious yet, look below. Chang Jian wrote in "Under the Fortress": The iron horse Hu Qiu came out of the Han camp and sent hundreds of troops to rescue Longcheng. Zuo Xian did not escape and the sword was broken, but the general was not in the army and the Han Dynasty was written. The army at home was sent to rescue the Dragon City. They guarded the border all year round. The seventh-term governor was naturally Li Guang.
