还辞
[hái cí]
In ancient Chinese literature, '还辞' often refers to someone returning and bidding farewell at the same time. The person might be going back after fulfilling a task or promise and saying goodbye, which carries the weight of a temporary parting or even permanent farewell. In today's online culture, people might adopt this nickname when they wish for new starts while being aware that some things are bound to come to an end, conveying feelings of nostalgia and moving forward.
