yang ka » yang fan, yang yao
yang xi » yang di, yang yi, yang jui
1 human » 3 human
2 human » 3 human

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((((yang ka) or (yang yang))) or (yang xi))nr ((1 human) OR (2 human)) demand age wang yong gun ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((yang ka) OR (yang yang))) OR (yang xi))nr ((1 human) OR (2 human)) demand age wang yong gun ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yang ka) or (yang yang))) or (yang xi))nr ((1 human) OR (2 human)) demand age wang yong gun ;*".
