Look at this man's mood. For example, I used to change wallpaper for a while, because my mood was different every day. Change some funny wallpaper when you are happy, such as a cat and a dog. Change some vent wallpaper when you are sad, such as changing wallpaper for some angry and tough words; Sometimes I send some inspirational wallpapers, such as Hugh, Eddie Peng Yuyan Yuyan and so on.

If this person hasn't changed wallpaper for a long time, it means that his heart has matured and he is no longer keen on the fun brought by wallpaper. He has gone beyond the idea of his student days, simply relying on changing wallpaper to attract others' attention, and at the same time, he has begun to care about others' opinions and gradually stabilized.

I remember the last time I changed wallpaper was the Mid-Autumn Festival last year. That night, I suddenly remembered many things, including my college classmates. The more I think about it, the more I feel. The Mid-Autumn Festival in my freshman year was really embarrassing and I didn't want to mention it.
