Li Tai
In 636, Li Tai's title was changed to Prince of Wei (魏), and he was made the commandant at Xiang Prefecture (相州, roughly modern Handan, Hebei), but again, he was not sent there, but remained at Chang'an. By this point, Emperor Taizong had begun to favor Li Tai greatly for his literary talent, he permitted Li Tai to retain a staff of scholars, and also, because Li Tai was obese, allowed him to ride a litter into the palace rather than walk. When rumors reached him that the high-level officials dishonored Li Tai, he grew angry at them, but relented after the chancellor Wei Zheng pointed out that, in fact, according to Confucian ceremonies, those high-level officials were in fact supposed to be higher in rank than Li Tai. In 637, Emperor Taizong made the senior official Wang Gui, a one-time chancellor, Li Tai's teacher, and he ordered Li Tai to honor Wang as if he were honoring his own father. Li Tai did so, and Wang accepted this. In 640, Emperor Taizong personally visited Li Tai's mansion, and to celebrate the occasion, Emperor Taizong pardoned the minor criminals of Chang'an, exempted Li Tai's neighborhood of its taxes for one year, and gave awards to Li Tai's staff members and the seniors in Li Tai's neighborhood.
