孟昶
In 962, Meng Chang created his son Meng Xuanzhe the Prince of Qin Crown Prince. For reasons unclear to history, Meng Chang also ordered that the new crown prince's attendants and people who announced his arrival should refer him as "His Imperial Highness" rather than "the Crown Prince." Li Hao, believing this to be irregular, argued against the order, and the order was rescinded.
