Before making a decision to hire a domestic helper, you should base your consideration on your lifestyle, culture, family size, and needs. Indonesians speak Cantonese better, and hence Indonesian domestic helpers are a better option for taking care of the elderly.
Indonesians are generally simple and obedient. The biggest cultural difference between Indonesia and Hong Kong is religion. June is the Indonesian New Year, and the Islamic Indonesian maids usually start fasting one month before the New Year, which means they cannot eat or drink from sunrise to sunset. They usually start fasting at an early age, and their bodies have generally adapted to such culture, so employers would not have to worry about affecting their work.
