An evil son and a lonely minister
The villains and orphans refer to those who are alienated and isolated from each other and those who are out of favor. From a dream of Red Mansions by Cao Xueqin in the Qing Dynasty.
Source: the 120th chapter of a dream of Red Mansions by Cao Xueqin in Qing Dynasty: "although things have been decided before, there is nothing to do, but it is not necessary to appoint all three words, that is, the evil son and the orphan, the righteous husband and the chaste wife."
