Li Shimin: "I want to repair the Luoyang Palace!" Zhang Xuan Su: "Your Majesty! When Afang Palace was completed, the Qin Dynasty fell; when the Zhang Hua Palace was built, the Chu people left; when the Qianyang Palace was finished, the Sui Dynasty collapsed. Please be cautious!" Li Tai: "I want to build the Wanshang Temple!" Fang Xuanling: "Your Highness, as long as the money isn't from the imperial treasury and doesn't burden the people with corvee labor, please feel free." Li Shimin: "..." This is a story of extreme farming and extreme spending during the Zhenguan era. It's a story of a person who eats, drinks, and waits for his elder brother's rebellion to be quelled, then inherits the family business. It's a story that continues the prosperity of the Tang Dynasty. It's a story about offering sacrifices to Mount Tai.
