houng gun » hyoung gun
yang fan » zhang fan, yang dean, yang yang
one bank » money bank, die bank, one book

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: ((yang fan) OR (yang yi))nr 3 human ((one bank) OR (gene bank)) can houng gun ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang fan) or (yang yi))nr 3 human ((one bank) OR (gene bank)) can houng gun ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang fan) or (yang yi))nr 3 human ((one bank) OR (gene bank)) can houng gun ;*.
