Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
lang dai » lang hai, lang mai, lang chai
lanh dai » lanh dao, lanh hai, vanh dai
sach va » sach xa, sach ha, sach dao
cua tre » cua te, cuu tre, dua tren
te sach » toc sach
cao xuc » cam xuc, cao duc, cao suc
hieu va » lieu va, hieu qua
va nang » van nang, da nang, cam nang
va cao » va cac, va co, va dao
xuc va » duc va, tuc va, luc va
x hoi » xa hoi, o hoi, x ho

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sach va nang x hoi. hieu va cao xuc va ((lanh dai) or (lang dai)) ((cua tre) OR (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach va nang x hoi. hieu va cao xuc va ((lanh dai) OR (lang dai)) ((cua tre) OR (cua triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach va nang x hoi. hieu va cao xuc va ((lanh dai) or (lang dai)) ((cua tre) OR (cua triet))*".
