Empress Zhangsun
In 632, Emperor Taizong was about to marry the Princess Changle to Zhangsun Wuji's son Zhangsun Chong (長孫沖). As the princess was born of Empress Zhangsun and was his favorite daughter, Emperor Taizong ordered that her dowry had to exceed that for his sister, the Princess Yongjia. The chancellor Wei Zheng advised against it, pointing out that this was contrary to Emperor Ming of Han's observation that his sons should not be as honored as his brothers. Emperor Taizong agreed and also informed Empress Zhangsun, who was greatly impressed with Wei's honest advice, and therefore, after receiving permission from Emperor Taizong, she had her eunuchs send rewards of money and silk to Wei, praising him for his honesty. On another occasion, after Emperor Taizong returned from an imperial gathering, he was angry and yelled, "Let me find a chance to kill this red-neck!" Empress Zhangsun asked whom he was referring to, and he replied, "I am referring to Wei Zheng. He always finds a way to insult me in front of everyone in the imperial hall!" Empress Zhangsun retreated to her bedchambers and put on the official empress gown; standing solemnly, she prepared to bow to Emperor Taizong. He was surprised, and asked her what the reason was. She responded, "I have heard that only a most able emperor will have subordinates who have integrity. Wei shows this much integrity because you are an able emperor. How can I not congratulate you?" Emperor Taizong's anger turned to happiness, and he did not punish Wei. Later that year, on an occasion when Emperor Taizong and she personally visited Emperor Gaozu (who had then taken the title of "Taishang Huang" (retired emperor)) at his Da'an Palace (大安宮), they personally served a feast to him.
