At present, the society is stable, the economy is prosperous and the people live and work in peace and contentment. Is the sentence "born in sorrow and died in happiness" still of practical significance? The Chinese nation has always been famous for its diligence, courage and fearlessness. We ancients have long said, "Difficulties and hardships make you successful", "Be prepared for danger in times of peace, abstain from extravagance and save money", "Worry about the country and the people, live in peace and die peacefully", and so on. These cautionary sayings still have important inspiration for us today. Both history and reality show that it is difficult for a nation to stand on its own feet without the support of the spirit of hard struggle. A country without the support of the spirit of hard struggle is difficult to develop and progress; It is difficult for a political party to prosper without the support of the spirit of hard struggle. In the process of our development, hard work, as a powerful spiritual force, has always inspired us to be indomitable in the face of various difficulties and tests, hold our heads high and dare to win. It can be said that we started with hard work and achieved great things through hard work. Without hard work, we wouldn't be here today.
