Perhaps you should try some spelling variations:
di terrence » di erence, deal terrence
yang gan » yang fan, yang guang, yang dean
gan guan » yan guan, quan guan, fan guon
wong yue » wang yue, hong yu
dr rene » der rent
tian yi » qian yi, tian yu, tan yi
yi wong » yi rong, y wong, kie wong

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: yang gan guan ((dr rene) OR (di terrence)) tian yi wong yue ;~.
• Adding a wildcard symbol may retrieve word variants: yang gan guan ((dr rene) or (di terrence)) tian yi wong yue ;*.
