Two direct flights operated by China Southern Airlines are available daily from Manila to Guangzhou. However, it is hard to say as the airfare for international flight is various on different travel date. Thus, you are suggested to consult the airlines with your specific departure date.

Hi sir,
Do you happen to be from the Philippines?
Alright sir, thank you for the information but I actually don’t have the specific date of our trip since we are still processing for our student visas. Could you please give me some approximates?

The ticket price is about 2000RMB one way, but the detailed one still depends on different travel date. Anyway, you would better make an enquiry after getting your visa and having your departure date in mind.
