min long » min hong, pain long, min jeong
yuan zi » yan zi, yuan li, yuan fei

long du » long d, long do, long run

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: lang yan ((yuan zi) OR (yang li)) liu gang min long du ;~.
• Adding a wildcard symbol may retrieve word variants: lang yan ((yuan zi) or (yang li)) liu gang min long du ;*.
