I'm a Cambodain who is currently woking OverSea (Philippines)

Hello, I'm a Cambodian who is currently working over sea. I'd like to apply for tourist Visa in Cambodia to visit HK for this May since I'll on my Vacation in Cambodia during this April. i have called and asked the agent how can i get the Tourist entry permit for visit HK and they told me i can't, at least i need to have a bank deposit account in China around 10K USD. Is this information true? I have my personal saving entry permit account, can't i use my saving account as a proof of my financial support?

i'm looking forward for your kindly reply.
thanks.
