I am a filipino working in thailand need working visa going to china

hi... I am a Filipino. My wife and I are both working in Thailand.. Now our visa will be over at the end of April.. We are planning of working in Hohhot city. We have the employer and the employer is ready to send the necessary documents needed for Z type. Is it possible that I can get it here in Bangkok? What are the important documents needed for Z type.. Do they need a medical certificate? I am hoping for an asap reply.. thank you
