He Changed The Tang Dynasty

During the Zhenguan period, why were there square dances accompanied by pipa music every night in the streets of Chang'an, the capital of the Tang Dynasty

Why did the heroes of the forest in the tavern end up fighting fiercely over the outcome of a game of "Three Kingdoms Kill"?

Why do the princes and princesses in the Daxing Palace eagerly await the release of "Weekly Shonen Jump" magazine at the beginning of each month

Why do the carriages of Mercedes-Benz in the Tang Dynasty bear the inscription "Didi Carriage"?

I, Li Yi, the Ninth Prince of the Great Tang, only wish to engage in inventions and creations, explore technology, draw comics, earn some money, and incidentally deal with the Turks, Goguryeo, and the Japanese... Why have I been designated as the Crown Prince? Do not worry, allow me to recite a poem first
