cua triet » cua viet, su triet, va triet
doi cua » dai cua, hoi cua, dong cua
te sach » toc sach
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
te sac » te cac, te san
tuc va » thuc va, truc va, duc va
ve cam » ve cham, ve cac, va cam

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((te sac) or (te sach)) ky nang xa hoi. hieu ve cam ((tuc va) OR (tuc xa)) thanh doi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sac) OR (te sach)) ky nang xa hoi. hieu ve cam ((tuc va) OR (tuc xa)) thanh doi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sac) or (te sach)) ky nang xa hoi. hieu ve cam ((tuc va) OR (tuc xa)) thanh doi cua triet".
• Adding a wildcard symbol may retrieve word variants: ((te sac) or (te sach)) ky nang xa hoi. hieu ve cam ((tuc va) OR (tuc xa)) thanh doi cua triet*.
