I believe that you are translating directly from Chinese instead of thinking in English. As a foreign language learner, it is in your best interest to think in the target language, as this will avoid translation problems like this one.
"While" relates an unspecified duration of time in the past while "since" literally means "after that" and stress from a known point in the past until the present unless emphasizing up until a certain point in the past.
Interpret what you wish to say directly into the target language or at the very least, paraphrase what you wish to say while thinking in the target language to avoid mistakes. Stylistically, don't forget to remember the concept of logic. If you heed my advice, just review the semantics of "arrive" and then paraphrase or interpret what you wish to say.
