hua chen » jui chen, yu chen, a chen
wan yan » wang yan, wai yan, wang yang

• If you are trying to use Boolean operators, they must be ALL CAPS: ((wan yan) OR (nan yan)) yaa hua chen sang minh ((wong shiu) OR (cong shu)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wan yan) OR (nan yan)) yaa hua chen sang minh ((wong shiu) or (cong shu)) ;".
