do i need to apply for tourist visa, my nationality is filipino?

Mildred, you do need one entry permit for China, but not the toursit type because you are going to attend the Canton Fair. Instead, you should apply for a business M type. First you should get an invitation letter online thorugh the official website of the fair. Then prepare your passport, a photocopy of the passport, a completed application form, a bare-headed photo, the original and photocopy of your work permit in Kuwait, and a bank statement. Then go to the embassy and apply for the M type.
