I am a Muslim studying in China and there is only one mosque in my city. They only open it for Jumu'ah prayer but close it thereafter. In this situation, are we allowed to pray at home?
Bismihi ta'ala
According to the view of our esteemed jurists, attending Salat al-Jumu'ah (Friday Prayer) is not wajib, but only Mustahab, and you are able to either attend, or pray your Dhuhr and 'Asr at home. You have this option to choose.
Of course, it is always recommended to pray in the form of jama'ah, or congregation, so it is encouraged to try to pray your wajib prayers in jama'ah in any opportunity you have.
With prayers for your success.
