• If you are trying to use Boolean operators, they must be ALL CAPS: wing ((dinh tung) OR (yan guan)) wu xiao zhang li ((((yang jin) OR (yang jun))) OR (song jin)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing ((dinh tung) or (yan guan)) wu xiao zhang li ((((yang jin) OR (yang jun))) or (song jin)) ;~".
• Adding a wildcard symbol may retrieve word variants: wing ((dinh tung) or (yan guan)) wu xiao zhang li ((((yang jin) OR (yang jun))) or (song jin)) ;*.
