What's the best song for Teacher's Day and Thanksgiving Day?

Grateful heart I came from an accident, like a grain of dust. Who can see my fragility, where I come from, and where my feelings go? Who will call me next? Although the world is wide, this road is difficult. I have seen all the ups and downs in this world. How much love do I have and how many tears do I have to shed? God knows I won't give up. Grateful heart, thank you for accompanying me all my life, and let me have the courage to be my own grateful heart. Thanks to fate, flowers bloom and fall, and I will cherish me as if I came by accident. A grain of dust, who can see my weakness, where I come from and where my feelings go? Who will call me next? Although the road is wide, it is difficult to walk. I have seen all the ups and downs in this world. How much love do I have and how many tears do I have to shed? God knows I won't give up. Thank you for accompanying me all my life and giving me the courage to be my grateful heart. Thank you for accompanying me all my life, so that I will cherish my grateful heart.
