Perhaps you should try some spelling variations:
ban thanh » ban hanh, ban hang
cua triet » cua viet, va triet
thanh tra » thanh toan, thanh hoa
su triet » su viet, su tien, ve triet
lang xa » lang ha, dang xay, lang van
hieu va » lieu va, hieu qua
cam duc » cam xuc, cao duc, pham duc
duc ban » duc tan, duc van, dua ban
sac ky » cac ky
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 ((sac ky) or (sai ky)) lang xa hoi. hieu va cam duc ban thanh tra ((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 cam duc ban thanh tra ((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 cam duc ban thanh tra ((cua triet) OR (su triet))".
• Adding a wildcard symbol may retrieve word variants: te ((sac ky) or (sai ky)) lang xa hoi. hieu va cam duc ban thanh tra ((cua triet) OR (su triet))*.
