Answer 2

"过去再见" or "告别昨日" are both good choices for a username that expresses saying goodbye to the past.
If you want to express a sense of starting anew or having a fresh start, you could consider usernames like "NewBeginnings," "freshStart," or "clean slate."
If you're looking for inspiration, you can always combine different words or ideas to come up with something that's unique to you, like "MoveOn," "GoneForward," or "FutureMe."
Just make sure your username is representative of the person you want to be online, and most importantly, easy to remember and spell!
