In 1972, Yu Guangzhong, a well-known Chinese poet from Taiwan wrote, 'now my nostalgia looms large to be a shallow channel. Here am I. And there... my mainland.' These lines are outpouring emotion of a countryman in Taiwan for the mainland. Then what has kept Taiwan compatriots away over the shallow Strait? And how did the Taiwan question arise?

The Taiwan question is essentially a remnant of China's civil war and is China's internal affairs. After World War II, Taiwan was returned to China de jure and de facto. On October 1, 1949, the People's Republic of China (PRC) was founded, and the Government of the PRC became the sole legal government representing the whole of China and the sole legitimate representative of China in the international community. As a natural result, the government of the PRC should enjoy and exercise China's full sovereignty, which includes its sovereignty over Taiwan.
