Specific to the party and Government departments, especially the cadres working in the Central and State organs, mass is the 1.3 billion Chinese people, work for the party members and cadres, masses are the land within the jurisdiction of the common people. The second ch

35、aracteristic of the masses, is that we have common interests. Masses are manifestations of each specific people, but the crowd is a comprehensive political concept, refers to people with common political and economic interests in the period of social transformation, social differentiation between the interests of the masses is large, if you do not find the interest in doing mass work, the party members and cadres, will be in a passive position. The third characteristic of the masses7
