how to get macau entry permit for srilankan passaport?

Dear, I’m afraid you cannot go there by your domestic helper’s entry permit. You should apply for an entry permit to Macau. First, prepare relevant required materials such as your passport and its copy, the application form, financial support proof, transportation and accommodation arrangements, travel purpose to Macau as well as your HK residence permit or entry permit. And then submit your application to the Office of the Commissioner of the Ministry of Foreign Affairs of PRC in HK SAR and apply for it.
