Heroes and models, the shining coordinates of the Chinese nation; Meritorious service and honor are the spiritual driving force to encourage the progress. We will form a good situation in which heroes emerge in large numbers in the new era. "The great era calls for a great spirit, and the lofty cause needs the guidance of an example." The advanced deeds and great deeds of meritorious models are inspiring the whole party, the whole army and the people of all ethnic groups to forge ahead, make contributions and make contributions, and gather the magnificent force of high spirited progress. Qian Qihu, "he is a protection engineering expert who strengthens the army with science and technology and casts a shield for the country, the founder of modern protection engineering theory and the founder of protection engineering discipline"; Nie Haisheng, "he is a heroic astronaut who is determined to serve the country and make three rounds of space". The advanced deeds of the three heroes and models of the people's army once again aroused warm repercussions throughout the army and among the people throughout the country. A nation with hope cannot be without heroes, and a country with a future cannot be without pioneers. This is a far-reaching consideration for promoting the great cause of Rejuvenation - on October 1, 2019, Tiananmen Square was red flag hunting and blooming. A grand meeting was held to celebrate the 70th anniversary of the founding of the people's Republic of China. Accompanied by the affectionate melody of Ode to the red flag, when the "salute" square composed of 21 concierge cars, carrying representatives of heroes and models who have made outstanding contributions, drove slowly past Tiananmen Square, the whole audience rose spontaneously to salute the heroes. "It is magnificent, magnanimous and graceful, orderly and harmonious.". The grand ceremony of the golden age, the supreme glory, inspires the hearts of the party, the army and the people, and stirs up the patriotic feelings of not forgetting the original intention and working together. We should honor the country with courtesy and lead the people with encouragement. I think deeply, and I am here
