Perhaps you should try some spelling variations:

thanh viec » thanh vien, thanh nien, thanh vinh
cua triet » cua viet, su triet, va triet
hieu van » hieu va, thien van, lieu va
nam tuc » nam thuc, nam truc, nam tu
nang xa » nang x, lang xa, nang ma
tuc va » thuc va, truc va, tuc xa
tu san » thu san, tu ban, tu can
tu sac » tu sach, tu cac, tu bac

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

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