emphasize some points :)
1. 过了几天：after a few days。前几天：a few days ago。

2. 回家=go back home, return home （No need “去” here.）

3. “A foreigner who looks like a traveler” should be “一个看起来像一个旅行者的外国人”. (There is no Attributive Clause in Chinese, we put the modifier-- “looks like a traveler”-- before the NONE(here “a foreigner”), then connect them by using “的”. Some degree like this: A “looks like a traveler” ’S Foreigner.(一个“看起来像一个旅行者”的 外国人)  

4. We don’t say “没会”, but “不会bu hui”。
