"Grateful heart, thank you, my life, let me have the courage to be myself. Grateful heart, thank fate, flowers bloom, I will cherish. " This song made me understand that without sunshine, there would be no warmth; Without water, there is no life; Without parents, without ourselves; Without affection, friendship and love, the world will be lonely and dark. In order to get rid of it, we need a grateful heart.

Fallen leaves hover in the air, composing a grateful movement, which is the gratitude of the tree to the earth that nourishes it; Baiyun floats in the blue sky and draws these moving pictures, which is Baiyun's gratitude for raising the blue sky. There will be a colorful society because of gratitude, and sincere friends because of gratitude?
