The heart of gratitude. As contemporary college students, our excellent environment today is created by society, and our parents have given us food, clothing, shelter and transportation. We should be grateful, grateful to our parents, grateful to a good society, and give us the opportunity to learn happily and grow up healthily. In short, contemporary college students have a long way to go. They need to stick to themselves, seize opportunities, turn cultural knowledge into development forces and make contributions to social progress.
