I hope you don't mind me replying in English.
Well actually you need to write you are born in the year of 1993 or above in order to sign up for Facebook. For Facebook requires High School Students ( F.3 in HK) in order to sign up. So either you make up your year or else you can't sign up. I am afraid that's the only way... Also not all schools in HOng Kong have a network in Facebook.
NOTE: If you really happen to write 1994 and somehow can sign up, please delete that account and start a new one. My sister wrote 1995 before and then her account got disabled forever.
