Ms. Nimota, Non-Irish passport holders are supposed to apply for any type of Chinese visa in the Chinese Embassy or Consulate in their home countries, with the exception that one is residing and working in Ireland. You study in Ireland, so I'm afraid your application maybe denied by the Chinese embassy.

The requirements for tourist visa (L visa)application are:
one completed visa application form, one recent photograph for passport, passport valid up to at least six months with blank pages, the two-way flight details and itinerary
