Where Is Chang'an?

In the eleventh year of Yonghe, the snow was very heavy, Wei Zhao's knife was very cold, and Pei Zhao's wine was very hot. They agreed to build a new Chang'an. Later—— Chang'an became the words on the monument, and they became the ashes of the history books. "I want no more doors in this world!" "I want this world to be peaceful everywhere!" The vows made by the two teenagers eventually became the most ironic footnote in the history books ten years later. Intention: Idealism compromises with reality, and the dragon slayer will eventually become a new dragon.
