From my understanding our parents don’t need money or giving them material things. I believe what would make them happy is to see us becoming upright and responsible individuals who can take care of themselves. Or when we study well, for instance score good grades at school, and most importantly work hard and succeed in our daily activities. Or being self-reliant, accountable, focused and respectful, we give our parents a sense of gratitude that their parenting role was worth the effort. In the above ways, my parent will feeling proud of us, they feel their efforts are not in vain. I think this would be the best way to repay them back for their love and sacrifices.

Hi .......,
It's great to hear from you. I’m writing to tell you about my mum.
Of all family members, Mum is the one who I love most. She's 45 years old. She's a teacher so she is always busy with students’ notebooks. In her freetime, she loves cooking and reading books, especially foreign novels. Her favourite book is "Gone with the wind". I have read it and it's really an interesting book. She sometimes makes Banh Khuc – my favorite dish. I'm fascinated by her delicious dishes. In the evenings, she helps me with my homework. She explains very gently so I can understand the lessons easily. I love her so much.
What about you? Tell me!
Please write to me soon.
Best wishes,
.........
