Put it at the very start of an edit, then follow it with a short reaction sound once the greeting has landed, such as a Bruh for a deadpan reply or a Goofy Ahh for a sillier turn, so the opener sets up the next beat instead of competing with it.
关于此声音
This is a short spoken greeting, lasting about a second and a half, in which a relaxed voice says 'Yo, what's up, guys?' in a friendly, informal tone. It feels warm, upbeat and welcoming, like the start of a video or a message to friends, and it sets a laid-back mood before anything else begins.
