Extended data:

The National Congress of the Party of China and its Central Committee are the highest leading organs of the Party of China. Held once every five years, convened by the Central Committee. If the Central Committee deems it necessary, or more than one third of provincial organizations request it, the National Congress can be held in advance; If there are no special circumstances, it shall not be postponed.

The two sessions are the general names of the National People's Congress of the People's Republic of China and the China People's Political Consultative Conference held over the years since 1959. Because the duration of the two sessions basically coincides, it is of great importance to the operation of the country, so it is called "two sessions" for short. From the provincial level to the central level, the sessions of the CPPCC plenary session and the NPC plenary session basically coincide, so the names of the two sessions can be applied to the whole country and all provinces (cities and autonomous regions) at the same time.
