Chinese business visa in Turkey for Syrian

Hi! I'm holding a Syrian passport, taking a legal war refuge in Turkey and currently working in a company here. I need to go on a business trip to China. I got the invitation letter from a Chinese company, a reference letter from Turkish company, and a completed application form. Do I also need to offer other materials, for example, bank account records, plane tickets, and tax records in Turkey? And can I apply visa here in Turkey with my war refugee certificate? Thanks.
