tang meng » tang zheng, gong meng, tang min
yuan linn » duan lian, yuan li, yuan ming
ong cheng » zong cheng, ong chong, dong sheng

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: taizong tang meng ((yuan lin) OR (yuan linn)) yang di ((hong cheng) OR (ong cheng)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "taizong tang meng ((yuan lin) or (yuan linn)) yang di ((hong cheng) OR (ong cheng)) ;~".
• Adding a wildcard symbol may retrieve word variants: taizong tang meng ((yuan lin) or (yuan linn)) yang di ((hong cheng) OR (ong cheng)) ;*.
