It that because the local people speak Cantonese?! No special Buddha lips. Wong Tai Sin's golden stature is worshiped in the temple. You should by burning sticks when you enter and temple and then make wish using honorific words in your language, hoping he can bless you and make your wish come ture. For prayers, language is not importance, the point is that they should be sincere. There are many procedures, such as shake the bamboo cylinder and take the fortune stick, and ask for the answer on what's saying on the stick. You can follow the others and your guide (if you are in a group) will tell you how to do it.
