How to apply for chinese visa

Dear Sir or Mrs,
First I want know how can I get to the chinese embassy in Bangkok (if necessary i can get a map both in English and in Thai) or give me all possible details of the address. And what kind of other documents or additional papers apart from the application form and the copy of my passport and finally what is the cost for a single entry (because i doubted with the above informations maybe they are not updated)? Please help me. I'm student in Bangkok.
