It fully shows that the party has a very clear understanding of its own health problems under the new situation. Under the new historical conditions, the Party has always faced the "four major tests" of governance, reform and opening up, market economy and external environment, and the "four major dangers" of mental slack, lack of ability, alienation from the masses and negative corruption. To withstand the test and resolve the danger, the most fundamental thing is to establish a sense of urgency.

Only by firmly grasping this main line can we consciously work hard to strengthen the construction of the party's ruling ability. Strengthening the construction of the party's ruling ability focuses on leading bodies and cadres at all levels. The key is to promote leading bodies and cadres at all levels to improve their ability to lead scientific development, serve the people, respond to emergencies and control complex situations by strengthening education, training and practice. To strengthen the construction of the Party's ruling ability, we should take maintaining the flesh-and-blood ties between the Party and the people as the core, building a contingent of high-quality cadres as the key, focusing on reforming and improving the Party's leadership system and working mechanism, and strengthening the Party's grass-roots organizations and the team building in party member as the foundation.

Only by firmly grasping this main line can we consciously keep the party's advanced nature forever. Advanced nature is the life and strength of Marxist political parties. The advanced nature of the Party is not immutable. Being advanced in the past does not mean being advanced now, and being advanced now does not mean being advanced forever. It is necessary to translate the Party's advanced requirements into the practical actions of all Party comrades, implement them in all the Party's ruling activities, realize scientific, democratic and legal governance, unite and lead the people to build a well-off society in an all-round way, and realize the great rejuvenation of the Chinese nation.

Only by firmly grasping this main line can we consciously always ensure the purity of the party. The party's purity construction is an important foundation and inevitable requirement for maintaining and developing the party's advanced nature, and it is also a profound summary of our party's historical experience. Purity is closely related to progress. Maintaining the purity of the party is an important prerequisite to reflect the advanced nature of the party. Without purity, there is no progress. On the one hand, it is necessary to practice "internal strength" and ensure party member's firm belief in Socialism with Chinese characteristics and capitalism through ideological construction; On the other hand, we should consciously accept external supervision, establish a perfect power supervision and restriction system, build a scientific system and mechanism, severely punish and prevent corruption, and let power run in the sun.
