liu gang » liu gangs, liu yang, li gang
yuan zi » yan zi, yuan li, yuan fei

long du » long d, long do, long did

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: wing yan ((yuan zi) OR (((yang li) OR (yang xi)))) liu gang pain ((long du) OR (long run)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing yan ((yuan zi) or (((yang li) or (yang xi)))) liu gang pain ((long du) OR (long run)) ;~".
• Adding a wildcard symbol may retrieve word variants: wing yan ((yuan zi) or (((yang li) or (yang xi)))) liu gang pain ((long du) OR (long run)) ;*.
