When Emperor Wen of the Han Dynasty (漢文帝) suffered from a carbuncle, Teng Tung (鄧通), a courtier, sucked the infected part for the Emperor and thus Won the favor of the throne. What's more, the Emperor bestowed him mt. Copper and agreed to let him mint coins. Because of favoring Teng Tung, the Emperor estranged Chia Yih (賈誼); a talented and virtuous official. Owing to that Teng Tung had sucked the infected part. A few days late when the Empreor ordered the Crown Prince to do what Teng Tung had done, the Crown Prince appeared reluctand and felt grudged. When the Crown Prince acceded to the throne, known as Empreor Chieng (景帝), he confiscated all Teng Tung's property and let him die of povert and starvation. On his way back from attacking Korea, Euperor Wen of the T'ang Dynasty (also known as Taitsung 唐太宗) suffered from a carbuncle. Liu Chi (劉洎), a minister, paid him a visit and said after he came out, “His Majesty is suffering from a serious carbuncle, which caused us to feel greatly anxious and fearful.” Ch'u Sui-liang (褚遂良) a talented and virtuous countier, memorialized a false charge, saying that Liu Chi was trying to do what Yi Yin (伊尹) and Huo Kuang (霍光) had done. At that time Liu Chi was a confidaut of the Prince of Wei, Whereas Ch'u Sui-liang was the one of the Crown Prince. In the T'ang Dynasty, the inheritance of the throne was by no secure; besides, Emperor Wen himself had assumed the throne by taking from the legal Crown Prince. Therefore the Emperor wrongly believed Ch'u Sui-liang's memorial and ordered Liu Chi to commit suicide. Both the Emperors, to be frank, were sagacious rulers, but, alas, because of their suffering from carbuncles, so as to have caused political upheavals, that was really a trivial flaw on a piece of jade.
