Hi there, i have been trying to reach the chinese embassy for more than a week now and am only able to get automated responses :( i really hope you can help me asap..

i am a PAKISTANI passport holder, travelling to Malaysia via HONGKONG, my transit stay is less than 3 hours on the way there and also less than 3 hours on the way back.
I am holding permanent residence (PR) of Canada

Do i need any sort of visa?

Anxiously waiting for a reply
hope to hear from you soon
thankyou!
