pain gong » pain long, pains long, pain non
hand pain » hand part, hand vein
dong nan » dong yang, dong cao
dong bin » dann bin
yin hand » yin hang, eine hand, die hand
gong hui » tong hui, tong shui, wang hui
fa yin » fan ying
sin » sign, sind, skin

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: ((dong nan) OR (((((dong bin) OR (dong di))) OR (dong sin)))) ya fa yin hand pain gong hui ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong nan) or (((((dong bin) OR (dong di))) or (dong sin)))) ya fa yin hand pain gong hui ;~".
• Adding a wildcard symbol may retrieve word variants: ((dong nan) or (((((dong bin) OR (dong di))) or (dong sin)))) ya fa yin hand pain gong hui ;*.
