关于这个问题，Dear teachers and friends,

Today is a special day as it marks the end of our time together in primary school. I want to take this opportunity to express my gratitude to all the teachers who have taught us and helped us grow over the years.

As we move on to the next chapter of our lives, I wish everyone the best of luck and success. Let's always remember the lessons we have learned and continue to strive for excellence.

Thank you, and goodbye!
