Perhaps you should try some spelling variations:
liang tan » liang dan, liang sun, wing tan
wang chun » tang chun, wang hua, wang hui
wong chun » fong chan, jong chan, tang chun
yang lin » yang jin, wang lin, yang li
yang jui » yang judy, yang di, yang yi
yang xi » yang di, yang yi
hai » hadi, haji, hari

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: liang tan ((wang chun) OR (wong chun)) gain ((((yang lin) OR (yang xi))) OR (yang jui)) dang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "liang tan ((wang chun) OR (wong chun)) gain ((((yang lin) or (yang xi))) or (yang jui)) dang hai ;~".
• Adding a wildcard symbol may retrieve word variants: liang tan ((wang chun) OR (wong chun)) gain ((((yang lin) or (yang xi))) or (yang jui)) dang hai ;*.
