唐太宗之叹唐太宗难过地对长孙皇后说:“我以铜为镜,可以正衣冠;以人为镜,可以明得失;以史为镜,可以知兴替。现在魏徴驾鹤西游,我少了一面人镜了。”皇后说:“陛下能说出这一番话来,可见平时对国事用心甚苦。只要陛下用心,何愁不能得到宝镜?”唐太宗为国家用心付出,遂有贞观之 Tang Taizong sighed that Tang Taizong said to the Queen’s grandson: “I use bronze as a mirror, I can dress up rightly; I can use the mirror as a mirror to understand the gains and losses; I can learn about history as a mirror. Now I’m driving west on a crane and I’m scared. A man’s mirror.” The Queen said: “Your Majesty can make such remarks. It can be seen that there is always a mischief on the state affairs. As long as you are careful, why can’t you get a treasure?” Tang Taizong paid for the country. Zheng Guanzhi
