hong jong » hong kong
tong hui » wang hui
yang jin » yang jie, yang jun, ying jin
jin wong » jin song, john wong, jin ying

• The words AND, OR and NOT may confuse the search; try adding quotes: "((ping wang) or (((hong wang) OR (hong jong)))) tong hui irene yang jin wong sau ;~".
• Adding a wildcard symbol may retrieve word variants: ((ping wang) or (((hong wang) OR (hong jong)))) tong hui irene yang jin wong sau ;*.
