Huangliang's sweet dream can be met but not sought.
"I always have some weird dreams. When I wake up from the dream, I don't remember anything. I just feel very uncomfortable... Very confused."
Have you also had this experience:
A strange intersection, a familiar person, a greeting that seems like it's a lifetime ago, you always feel as if something happened... You may have been here a long time ago...
Purpose: Don't be addicted to the virtual world, real life is the most important
