《资治通鉴·汉纪·汉纪二十一》
功过相等，如此也就算了。应该权衡功过大小而作出适当的决定。当初，太子刘骜从小就喜爱儒家经典，宽厚、博学、谨慎。可是后来却爱饮酒，喜欢安乐，元帝认为他没有能力。
初，太子少好经书，宽博谨慎；其后幸酒，乐燕乐，上不以为能。
If merits and demerits are equal, then so be it. We should weigh the merits and demerits and make an appropriate decision. In the beginning, Crown Prince Liu Ao loved Confucian classics while he was young, he was generous, widely learned, and cautious. However, he later loved to drink and preferred comfort, and Emperor Yuan believed that he was incompetent.
