In 1923, the former Qing emperor
Puyi summoned Zheng to Beijing in order to reorganize the imperial household. Zheng became a close adviser of Puyi and helped arrange for his flight to the
foreign concession at Tianjin after his expulsion from the
Forbidden City by General
Feng Yuxiang. Zheng remained loyal to the throne and secretly met with Japanese officials and groups such as the
Black Dragon Society to discuss a restoration of the Qing dynasty in
Manchuria. Following the
Mukden Incident and the
invasion of Manchuria by the
Imperial Japanese Army in 1931, Zheng played an important role in the establishment of
Manchukuo, becoming its first
prime minister the following year. Zheng also composed the lyrics of the
National Anthem of Manchukuo. Zheng had hoped that Manchukuo would become a springboard for the restoration of Qing rule in the whole of China, but he soon found out that the real rulers of Manchukuo, the Japanese
Kwantung Army, did not share his ambitions. As Prime Minister of Manchukuo, Zheng frequently disagreed with the Japanese Army leadership. In May 1935, he was pressured to resign from his office. Three years later, he died suddenly under unclear circumstances, which led to speculation that he may have been poisoned by the Japanese. He was accorded a
state funeral in April 1938. ==Legacy==
