Perhaps you should try some spelling variations:
cua triet » cua viet, va triet
su triet » su viet, su tien, ve triet
hanh tri » thanh tri, hanh tai, hanh trinh
tham luc » than luc, tham nuoc, tham thuc
va hanh » van hanh, va thanh, va danh
va tham » van tham, va cham, va thanh
hieu va » lieu va, hieu qua
lang xa » lang ha, dang xay, lang van
sac ky » cac ky
luc va » duc va, tuc va, loc va

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

• Performing a fuzzy search may retrieve terms with similar spellings: te ((sac ky) OR (sai ky)) lang xa hoi. hieu va tham luc va hanh tri ((cua triet) or (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sac ky) OR (sai ky)) lang xa hoi. hieu va tham luc va hanh tri ((cua triet) OR (su triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sac ky) OR (sai ky)) lang xa hoi. hieu va tham luc va hanh tri ((cua triet) or (su triet))".
• Adding a wildcard symbol may retrieve word variants: te ((sac ky) OR (sai ky)) lang xa hoi. hieu va tham luc va hanh tri ((cua triet) or (su triet))*.
