Visit to family member

i am a bi-government scholarship student (scholarship from the Governments of the Czech Republic and and my home country, Ghana) here in Prague. i hold a one year visa of the Czech Republic. My fiancee has been schooling in China for the past two years. infact we are traditional married (as in our tradition in Ghana) but not registered. i wish to visit her this winter break. What do i need to have? and are my chances bright?
