First, the masses have a "clear account" in their hearts, which broadens the source of clues. Through the publicity of the "three affairs", the masses clearly grasped the situation of party affairs, government affairs and village affairs. Once problems are found, they actively report them, effectively broadening the sources of clues.

The second is to give full play to the role of mass supervision and effectively prevent "micro-corruption" at the grassroots level. At the grass-roots level, it often happens that the superior supervisor is subject to property, the department supervision is not in place, and the supervision at the same level is weak. The "three things" open system makes up for these shortcomings and provides a platform for mass supervision. Some grassroots cadres, taking advantage of the weaknesses of farmers and herdsmen's low education level and inaccurate policy grasp, abuse their rights, seek personal gain and act indiscriminately. The implementation of the "three affairs" open system forces these cadres to "put their rights in the cage of the system" and effectively prevent the occurrence of micro-corruption at the grassroots level.

Third, the "transparency" of work has improved, forcing cadres to improve their work style. "Three services". Not being open, not being open, and not being open are all manifestations of inadequate implementation of responsibilities and weak sense of serving the masses. Doing a good job in the propaganda of "Three Things" requires cadres to change their work style, act positively, keep close contact with the masses, and improve their ideological consciousness of serving the masses.
