Are you holding filipino passport? How long will you stay in Hk? May I know your travel purpose? Filipino passport holders don't need any visa to Hk for less than 14 days for each entry.

If you mean the financial proof of adequate funds for your Hk trip. There is no specific regulation about this on the official website of HK government. If you do want to know, you may contact the HK Immigration Department directly through phone:(852) 2824 6111 or by fax (852) 2877 7711.
