Grand Duke, Prince, Emir and Sultan. There are also a few nations where the exact title and definition of the position of head of state was vague. While the Chinese Cultural Revolution, after the fall of Liu Shaoqi, was the president of the state (Chinese president), no successor was appointed, so the functions of the head of state were collectively entrusted to the Standing Committee of the National People`s Congress. This situation changed later: 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 function with limited power, the symbolic role of a head of state is now usually exercised by Xi Jinping, also general secretary of the Communist Party (head of the Communist Party) and chairman of the Central Military Commission (Supreme Military Command), making him the most powerful person in China. For non-executive heads of state, there is often some degree of censorship on the part of the politically responsible government (such as the head of government). This means that the government quietly approves the agenda and speeches, especially when the Constitution (or customary law) assumes any political responsibility by granting the Crown inviolability (in fact also political pruning), as in the Kingdom of Belgium from the beginning; in a monarchy, this can even be extended to some extent to other members of the dynasty, especially to the heir to the throne. A head of state can take power by force or revolution. This is not the same as the use of force to maintain power, as practiced by authoritarian or totalitarian leaders. Dictators often use democratic titles, even if some call themselves monarchs. Emperor Napoleon I is an example of this. by France and the King Drawn from Albania. .
