Care about "national affairs" and shoulder "national responsibility" ■ Ma Kejun "It's a blessing in life to be born in a great era. Young people who study abroad and return home should be concerned about 'national affairs' and shoulder' national responsibilities'." President Xi recently wrote back to young scholars who study abroad and return home at Nanjing University, affirming their childlike heart and ambition to serve the country, encouraging them to serve the country, serve the people and strive to make new and greater contributions. "People must be really patriotic, and then they can use great things." Patriotism is the deepest and most lasting emotion, and serving the country is the simplest and most affectionate confession to the motherland. Action comes from the heart, and strength comes from ambition. At that time, it was the broad feelings of serving the country sincerely and revitalizing China that made a large number of patriotic scientists such as Qian Xuesen, Deng Jiaxian and Wang Ganchang resolutely return to work for the country and never regret serving the country all their lives. "One sword, three feet." The value of soldiers is closely related to national interests, and the mission of soldiers is closely related to the fate of the country. Only by putting our family and country in mind, carrying the responsibility on our shoulders, being brave in struggle, willing to contribute, and determined to serve the country and strive to strengthen the army, can we live up to our mission and trust. Soldiers shoulder the responsibility for national security. Patriotism is never a slogan, but a concrete action. As a revolutionary soldier in the new era, his duty is sacred and his mission is glorious. He must have a great self, be sincere, never forget his original intention of joining the army, strengthen his ambition to serve the country, practice hard skills to win wars, and resolutely complete the missions and tasks entrusted by the party and the people.
