The current position of President in mainland China is virtually
a ceremonial one, but since 1993 it includes a position as General
Secretary of the Chinese Communist Party. The President may serve
for a maximum of 2 five-year terms, for a total of 10 years.
The longest-ruled emperor in China ruled 61 years. Now, The
constitution of the People's Republic of China stipulates that a
president serve a five-year term and can be reelected only once. So
a president of China now can not serve for more than 10 years.
