Tell us to keep our initial heart, keep working hard, always keep youthful vitality, have lofty aspirations and pursuits, always keep an enterprising attitude, and constantly strive to realize our own life value. Don't forget the ideas you pointed out to us on your own initiative. We should always adhere to our original beliefs and ideals and not be shaken by external interference and temptation. Youth always means keeping the vigor and vitality of young people, always full of passion and enthusiasm, and full of love and enthusiasm for life and work. "Don't forget your initiative, the youth and vitality of your mind will always be teenagers in the next century" means that people should keep their initial beliefs, forge ahead, be ambitious, and remain childlike when they come back no matter how long they go out.
