In 937, Xu Zhigao had Yang Pu yield the throne to him, ending Wu and starting
Southern Tang. He created Princess Song empress. It was said that, as empress, Empress Song often advised Li Bian regarding proposals and reports that his officials submitted to him, and he found her advice beneficial, stating, "Even as my own thoughts had not reached the right conclusion, the Empress has already understood correctly." Li Bian died in 943, and was set to be succeeded by Li Jing. The
chancellor Sun Sheng, however, was concerned at the possibility that a number of Li Jing's close associates, including Wei Cen (魏岑),
Feng Yanji, and Feng Yanlu (馮延魯), whom he considered wicked, might take power. He therefore wanted to manufacture an order in Li Bian's name ordering that Empress Song serve as regent. However, Empress Song herself did not find this appropriate, pointing out that she did not want to be like
Wu Zetian, and the imperial scholar Li Yiye (李貽業) also found it unlikely that Li Bian, who often spoke against the idea of women in control of the state, would authorize such a regency, and Sun thus dropped the idea, fearing a public dispute. == As empress dowager ==
