I am a Ghanaian and i want to travel to china and work over there. but i dont have any link

Benjamin, it's possible for you to go there as a tourist. You need to book round-trip tickets and hotels in advance. Then submit the photocopies of these ticket and hotel room bookings along with your passport, passport copy, application form, and recent photo to the embassy. In this way, you don't have to know someone in PRC.
