Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
tham tuc » tham thuc, thai tuc, nham thuc
cua tre » cua te, cuu tre, dua tren
danh vi » hanh vi, dinh vi, danh di
va danh » va dinh, va dan, va hanh
va tham » van tham, va cham, va thanh
hieu va » lieu va, hieu qua
nang xa » nang x, lang xa, nang ma
can ky » van ky, ban ky, tan ky
tuc va » thuc va, truc va, tuc xa
dan ky » van ky

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

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