Perhaps you should try some spelling variations:
dang dinh » dang anh, sang minh
dinh tuan » binh thuan, dinh tung, anh tuan
yang jin » yang jie, yang jun, ying jin
tuan vu » thanh vu, tuan hua
vu gain » you gain, run gain, via gain
wang di » yang di, wang d, wang li
hai » hadi, haji, thai

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: dang dinh tuan vu gain ((yang jin) OR (wang di)) ((dang hari) OR (dang hai)) ;~.
• Adding a wildcard symbol may retrieve word variants: dang dinh tuan vu gain ((yang jin) or (wang di)) ((dang hari) or (dang hai)) ;*.
