There are also a few nations in which the exact title and definition of the office of head of state have been vague. During the Chinese Cultural Revolution, following the downfall of Liu Shaoqi, who was State Chairman (Chinese President), no successor was named, so the duties of the head of state were transferred collectively to the Standing Committee of the National People's Congress. This situation was later changed: the Head of State of the PRC is now the President of the People's Republic of China. Although the presidency is a largely ceremonial office with limited power, the symbolic role of a Head of State is now generally performed by Xi Jinping, who is also General Secretary of the Communist Party (Communist Party leader) and Chairman of the Central Military Commission (Supreme Military Command), making him the most powerful person in China.
