Since economic reforms began in 1978, the Central Committee has usually been composed of the leading figures of the party, government, the provinces, and the military. In contrast to Party Congresses, which have always been essentially ceremonial exercises, full meetings of the Central Committee have occasionally emerged as arenas in which there were substantive debates and decisions on party policy. An example of this was the Third Plenary Session of the 11th CCP Central Committee in 1978, at which China formally embarked on a project of economic reform. Deng Xiaoping also attempted to increase the level of "intra party democracy" in the 1980s by introducing so-called "more candidates than seats" election method ("Cha'e xuanju"). The "Cha'e" method meant that not everyone who was nominated would be elected to the Central Committee.
