Any one of the following documents is ok: Invitation Letter or Confirmation Letter of Invitation issued by duly authorized Chinese institute, relevant formal business documents showing the activities the applicant will attend, Conference Notice, Invitation of Trade Fair, Business License of Foreign-invested Enterprises in China with the applicant's name on.
Other basic documents required are passport, application form, photo. BTW, you should prepare a Personal Written Statement with details such as Destination; name, address and contact number of the inviter.
