In 21 AD, Empress Wang died. After her death, Wang Mang discovered that one of Empress Wang's ladies in waiting, Yuan Bi (原碧), with whom he had an affair, had also had an affair with Crown Prince Lin, and that she had conspired with Crown Prince Lin to kill Wang Mang, because of Wang Lin's demotion. Wang Mang ordered Wang Lin to commit suicide by poison, but Wang Lin refused, and killed himself using a sword. Later that year, Wang An died as well. Wang Mang then announced that he had in fact two sons by female servants, whom he then created dukes.
