Li Hong
During the reign of Emperor Taizong's son Emperor Gaozong, Wang Jishan served on the staff of his son and crown prince Li Hong. Once, Li Hong gathered his staff members for a gave of "zhidao" (擲倒, probably traversing on one's hands with feet in the air). When Wang's turn was up, he opined that there were people whose responsibilities were to entertain the crown prince, and that it was inappropriate for staff members to be participating in the game. Li Hong thanked him and excused him. When Emperor Gaozong heard this, he awarded Wang with silk and made him a commanding general of the imperial guards, commenting, "I know that you are faithful and diligent, and that is why I give you an office of the third rank. Other people need to be searched before they could enter the palace, but you are allowed to holster a large sword to be by my side. Do you understand the honor that this is?" Soon thereafter, however, Wang was dismissed on account of illness, but later on was made the minister of military supplies (衛尉卿, "Weiwei Qing").
