What are the requirements in getting working visa? My employer asked me to inquire about this.Thanks

Javier, first you should ask your employer in China to get a work permit and an invitation letter or invitation confirmation letter fom a duly authorized unit for you. Then with the work permit and the letter, you can apply for a Z type at the embassy. Things you may be required to hand in are your passport, a photocopy of the data page of your pssport, a filled application form, a passport style photo taken within six months, and the work permit and the letter. If you are going to China for the first time, you should also provide a financial standing proof, such as BIR-stamped income tax return form, bank deposit certificate, professional ID, etc.
