Hi i'm a filipino citizen, i would like to get a visa to Beijing, China, What should i do first?

You need to prepare documents first, such as invitation letter, round-trip ticket and hotel bookings. BTW, if you visit for the first time, bank certificate of deposit balance including the past 6 months history of your bank account and the receipt for payment of this certificate, or BIR-stamped income tax return form, or letter from your employer detailing your salary and the length of your employment is required, or business registration certificate if you are the owner.
