Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
van tuan » van quan, van ban, anh tuan
te sach » toc sach
sach ky » sac ky, sach y, sach ty
nang xa » nang x, lang xa, nang ma
duc van » duc va, duc tan, duc manh
cua tre » cua te, cuu tre, dua tren
ve cao » ve bao, ve cac, ve co
va cao » va cac, va co, va dao

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 ky nang xa hoi. hieu ((ve cao) OR (va cao)) duc van tuan le ((cua tre) or (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang xa hoi. hieu ((ve cao) OR (va cao)) duc van tuan le ((cua tre) OR (cua triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang xa hoi. hieu ((ve cao) OR (va cao)) duc van tuan le ((cua tre) or (cua triet))*".
