Plan to go back to china as tourist

I've worked there for six years and i lost my passport. i applied for new one and new working visa and that was it and came back here in the Philippines. And now i'm planning to go back their as a tourist. Do the embassy only need a copy of my latest visa? The one who invited me is the school. What documents should i need to prepare?

Hope you can help me with this one. Thank you very much.
