yang john » young john, king john, yang jin
john song » john wong, john bonn, john ngosong
song shu » cong shu, song shin, tong shui
hua tan » hua ban
sin » sign, sind, skin

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((yang yang) or (((dong ping) or (dong sin)))) ya ((hua tan) OR (huan t'an)) yang john song shu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang yang) OR (((dong ping) OR (dong sin)))) ya ((hua tan) OR (huan t'an)) yang john song shu ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang yang) or (((dong ping) or (dong sin)))) ya ((hua tan) OR (huan t'an)) yang john song shu ;".
• Adding a wildcard symbol may retrieve word variants: ((yang yang) or (((dong ping) or (dong sin)))) ya ((hua tan) OR (huan t'an)) yang john song shu ;*.
