The difference between a Party congress and a Party congress is that a Party congress is only an important meeting convened by the Central Committee or the Party's local committees at all levels during the term of office of the Party committee when important issues need to be discussed and decided in a timely manner. The Party's National Congress is the highest leading organ of the Party. The Party's local congresses at all levels are the Party's local leading organs at all levels. The Party's committees at all levels are responsible and report to the Party's congresses at the same level.
 Legal basis
 Article 11 of the Constitution of the Communist Party of China The election of deputies and committees to the Party's congresses at all levels should reflect the will of the electors. The election is held by secret ballot. The list of candidates should be fully deliberated and discussed by the Party organization and the voters. The formal election may be conducted directly by means of a differential election in which the number of candidates exceeds the number of candidates to be elected. A preliminary election may also be conducted by means of differential election to generate a list of candidates before the formal election. Electors have the right to know about candidates, request to change candidates, not to choose any candidate or to choose another person. No organization or individual may in any way force voters to elect or not to elect a person. In case of any violation of the Party Constitution in the election of local Party congresses at all levels and grass-roots Party congresses, the Party committee at the next higher level shall, after investigation and verification, make a decision that the election is invalid and take corresponding measures, and report it to the Party committee at the next higher level for review and approval, and formally announce and implement it.
