In order to allow students to have a deeper understanding of Chat GPT, starting from the situation where students often encounter how to write a love letter and confess to the person they like, the Association of the Department of Membership Design designed the "Managing School Sends Happiness" activity to assist students to use Chat GPT to write love letters and make them on the spot The card was posted on the wish wall to show love, attracting hundreds of students to participate. I was very pleasantly surprised: "It turns out that Chat GPT can also write a love letter with both emotions!"
