Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hanh tai » thanh tai, hang tai, han tai
te sach » toc sach
sach ly » sach y, sach lo, sach ty
nang xa » nang x, nang ma, mang xa
lang xa » lang ha, dang xay, lang van
cam duc » cam xuc, cao duc, pham duc
va hanh » van hanh, va thanh, va danh
cua tre » cua te, cuu tre, dua tren
va cam » va cham, va cac, va cao

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 ly ((nang xa) or (lang xa)) hoi. lieu va cam duc va hanh tai ((cua tre) OR (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ly ((nang xa) OR (lang xa)) hoi. lieu va cam duc va hanh tai ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ly ((nang xa) or (lang xa)) hoi. lieu va cam duc va hanh tai ((cua tre) OR (cua triet))".
• Adding a wildcard symbol may retrieve word variants: te sach ly ((nang xa) or (lang xa)) hoi. lieu va cam duc va hanh tai ((cua tre) OR (cua triet))*.
