Analysis of information sources in references of the Wikipedia article "李宗仁" in Chinese language version.
When China's Nationalists retreated from their refugee capital of Chungking last November, Acting President Li Tsung-jen did not go with them. Instead, Li took a plane to Hong Kong, announced he would enter a hospital for treatment of an old stomach ailment. Ever since then, Nationalist China's fight against Communism has been directed by Chiang Kaishek, who came out of retirement to take over unofficially in Li's absence. Li tarried in Hong Kong for two weeks, then came to the U.S. for an operation, bringing his family with him.
