有缘再见
[yŏu yuán zài jiàn]
'You Yuan Zai Jian' implies 'if fate allows us, we shall meet again'. A slightly melancholic phrase implying a farewell without knowing if the people will ever encounter again. Maybe the user hopes that every departure or goodbye could still have another chance to reunite someday in the future. The choice of this ID may hint at personal experience or view on relationships.
