?Speaking of great dedication，I think first of all about the dedication of great men. Such as the great spirit of creation, the spirit of struggle, the spirit of unity, and the spirit of dreaming. These spirits are the great spirit of our Chinese nation. It is precisely because of these four great spirits that our country will become better and better. And these great spirits have gradually run through our modern lives. There are now many professions that are striving and working hard for these great spirits. These professions include doctors, nurses, teachers, scientists and so on. The great creative spirit teaches us to know how to innovate and discover new problems. The spirit of great struggle educates us to dare to struggle and work hard to move forward. The great spirit of unity teaches us to unite and struggle together. The spirit of great dreams teaches us to dare to pursue our dreams. Go forward with a dream. These great spirits sustain us in everything. Let's be a good person. ?
