Hi! I'm a Filipino and will be visiting HK for 4 days with my infant daughter, my partner, and my household helper. We all have a valid Philippine passport as well as roundtrip tickets back to the Philippines. Is there anything else I should bring with me such as important documents (ie. birth certificate, etc.)? I have traveled alone to HK before but this will be the first time I will be traveling with first-time HK visitors. Kindly advise me if there is anything else I need to bring with me. Thank you.
