minh gong » minh cong, min hong, ming kong
yang jui » yang judy, yang di, yang yi
gong hui » tong hui, tong shui, wang hui
yang xi » yang di, yang yi
li sang » le sang, li gang, li san

• The words AND, OR and NOT may confuse the search; try adding quotes: "wang liang ((yang xi) OR (yang jui)) li sang minh gong hui ;*".
