if she is originally from PH, then she goes back to PH (her hometown, not just manila), plus travel expenses, such as food she will need during her trip.... not macau. you have to pay her 1 month wages in lieu of notice, too.
but this depends on the reason for firing her. if it is due to gross negligence (ie. she left your baby alone and went grocery shopping), then you can terminate her without notice or payment in lieu.
