Li Yuanji
Li Yuanji was initially posthumously reduced to commoner rank. After Emperor Taizong took the throne, he posthumously created Li Yuanji the Prince of Hailing, with the unflattering posthumous name of La (meaning "ungrateful"). In 642, Emperor Taizong changed Li Yuanji's posthumous title to the greater title of Prince of Chao, and adopted his own son, by Consort Yang (Li Yuanji's widow), Li Ming (李明) the Prince of Cao (note difference in title) into Li Yuanji's line, as Li Yuanji's heir.
