QuickFox

I guess all the overseas students know this super app Quickfox, right? It can help you watch TV series, listen to music, play games, and go home with one click. It is especially suitable for people like me who must watch TV series while eating, listen to music when riding in the car, and play games all the time. Hahaha

The above apps can help you better adapt to studying abroad, improve your learning efficiency, and live and socialize more conveniently.
