How to write the opening and closing remarks of the auction?

Hello, everyone, the auction of XXX class begins now. The teacher who came to watch the auction today is the head teacher XXX, and we welcome him with warm applause. Today's auction is attended by students from Class XXX. I wish you a successful bid. The auction is about to begin. The items participating in the auction today include quill pens, red pens, correction fluid, notepad, post-it notes, mood books and time hourglass. Let's give you five minutes to discuss what you want to shoot.

Finally:

Students, all the items are auctioned at this time. Maybe some things are insignificant, but if you give them to your family and friends, you can sublimate their value. It not only contains affection and friendship, but you can proudly say to them, "I bought this with my grades at school!" " "

In that case, you will find that the value of this item is far higher than its value. Now I declare the "xxx-level auction" successfully concluded, thank you!
