"The great goal of all human efforts is to achieve happiness." So, what is happiness? The answers given by different people in different times can be described as thousands of differences: some people regard the fragrant cars and BMW, rich clothes and food as happiness, some people regard the promotion and wealth, and honor their ancestors as happiness... These have not been able to jump out of the limitations of material, narrow, and self-interest. In contrast, the Communists' concept of happiness is more broad, noble and meaningful. What is the Communist's concept of happiness? President Xi pointed out: "the greatest happiness in the world is to strive for the happiness of the people." Striving for the happiness of the people has broken through the limitations of material, narrow and self-interest, closely linked personal happiness with the interests of the country, the nation and the people, and linked happiness with the original mission. With this kind of mind, responsibility and realm, you will have lofty goals and pursue loftiness - what you do is not only to seek interests for individuals and families, but also to strive for the prosperity of the country and the happiness of the people, so that more people will be happy because of your efforts and dedication. In the Centennial journey of the party, it is precisely because of the sacrifice and dedication of millions of communists that today's country is prosperous and the people are happy and healthy. On the new journey of struggle, we should continue the Communist concept of happiness and always pursue "the greatest happiness in the world". The Communists' concept of happiness is broad. Our party has always adhered to the fundamental purpose of doing everything for the people, relying on the people, and serving the people wholeheartedly. From Shikumen to Tiananmen, from Xingye Road to Fuxing Road, all the efforts, struggles and sacrifices our party has made over the past century are for the happiness of the people and national rejuvenation. For this original mission, the Communists have high aspirations and strive to achieve "no less" on the road of pursuing happiness and stability and realizing a well-off society in an all-round way; The Communists have strived tirelessly. From standing up, becoming rich to becoming strong, they have run one stick after another. To continue the Communists' concept of happiness, we must always keep in mind that "rivers and mountains are the people, and the people are rivers and mountains". We should always carry out the people-centered development thought, and use our unremitting efforts to seek happiness for the people, rejuvenation for the nation, and great harmony for the world. In this way, we can win the trust and support of the people, and always grasp the strategic initiative and remain invincible. The Communists' concept of happiness is selfless. The Communist Party of China has no special interests other than the interests of the state, the nation and the people. During the revolutionary war years, countless martyrs fought bravely, one after another, and explained their understanding of happiness with the sacrifice and dedication of "I recommend Xuanyuan with my blood". What are they doing this for? The sentence "let our children and grandchildren enjoy the happiness of our predecessors" said by chenqiaonian before his death tells the true meaning of selflessness and the original intention of struggle. During the period of peace building, from guwenchang, who "made revolution without selfishness and devoted himself to the people", to Huang Dafa, who "I joined the party for the interests of the masses, not for personal interests"; From wangjicai, who has adhered to the isolated island for more than 30 years, to Libaoguo, who has been helping the poor in the Taihang Mountains for 35 years... Their selfless mind and great love for the party and the country have demonstrated the lofty style of selfless dedication of the Communist Party. To continue the Communists' concept of happiness, we must shed sweat, make painstaking efforts and contribute wisdom without complaint and regret for the interests of the country and the people. Such a life is a happy and meaningful life. The Communists' concept of happiness is a struggle. "Only a struggling life can be called a happy life." Happiness is not only material and spiritual satisfaction, but also labor and creation. The happiness of Communists is always connected with struggle. Struggle includes not only the heroism of "dying in national calamity, but also the persistence of" dripping water pierces the stone, and making contributions for a long time ", the great cause of" doing earth shaking things and burying celebrities with hidden names ", but also the commonness of" moss and flowers are as small as rice, but also learn from peonies ". Only when millions of people work together on different fronts and in different posts can we make a big "cake" of happiness and make the country richer and stronger and the people happier. To continue the Communists' concept of happiness, we must overcome the word "difficult", not be afraid of any difficulties, "the more difficult and dangerous, the more forward"; It is necessary to write a word "Heng", hold on to ideals and beliefs, "hold fast to the green mountains and do not relax", and create happiness in the struggle. The Communists' concept of happiness is realistic. "There is no doubt that the truth is true." From ancient times to the present, doing well and prospering the country is not only the standard of governing the country, but also the law of obtaining happiness. From Zhang side, who was "silent in handling affairs", to Lei Feng, who was "a screw that will never rust"; From jiaoyulu, who "lives in a sand dune and dies in a sand dune, to Zhang Lianyin, who" returned to his hometown to plant trees for 19 years and sow a green shade ", despite the continuous development of the times, being realistic and pragmatic has always been the true nature of the Communists. If you are not honest, you have no foundation; No matter what you do, there is no source of happiness. In the period of reform and social transformation, it is "easy for those who do hard work" and "difficult for those who do not". To continue the Communists' concept of happiness, we must have the self-consciousness of not seeking easy things and not seeking refuge. We must have the tenacity of grasping the iron with traces and stepping on the stone to leave our mark. With the feeling of "success does not have to be in me", we must write the performance of "I must have my own achievements". (Xinhua News Agency)
