Try "Wei", pronounced like "way". Usually used to say hello, but can be construed as rude depending on the audience. I find Hong Kong people sometimes react negatively to it. When you want someones attention "Wei" away at them, and it means "Hey". You can use "Ni Hao" more politely, but it literally means "you good?" and is used as a greeting.
