In 8 BCE, Emperor Cheng summoned several key officials to discuss with him who would be the more proper heir. The majority, perhaps seeing that Emperor Cheng was leaning toward Prince Xin, recommended him, citing the general rule of succession that when one lacked an heir, he should adopt a brother's child to be his own son and heir; one official recommended Prince Xing under the rationale that he was closer in bloodline with the emperor. Emperor Cheng, whose mind was fairly made up, created him Crown Prince Xin. In an act praised one as showing humility, Prince Xin declined the honor of living at the crown prince's palace, stating that he was only at the capital to serve Emperor Cheng until Emperor Cheng would produce an heir and that he should stay at the Dingtao mission in the capital.
