China's Visa information for Georgia citizen

Hi!
I’m Murvanidze Malkhaz, Georgian citizen, seamen. At end of July I have to join ship which will be in China. As my crewing agency told me, before traveling from Georgia, I need to get one for entrance in China and please inform me what documents I need to prepare for this purpose. (or pls. indicate some site, where I can found this information).
Thank You in advance. Sincerely Yours M. Murvanidze
