《旧唐书·本纪·卷十九》
虽然诚信还没有使人信服，在恭肃戒惧方面却不敢松懈，既无意在苑囿中玩赏，更无心去狩猎游乐，只是兢兢业业地一天比一天谨慎。
虽诚信未孚，而寅畏不怠，既绝意于苑囿，固无心于畋游，业业兢兢，日慎一日。
Although sincerity does not convince others, but on being respectful and fearful one would not dare to relax, with neither intention to enjoy in the gardens nor desire to go on a hunting trip, but to be conscientious and prudent each passing day.
