Perhaps you should try some spelling variations:
chet triet » chuyen triet, thuyet triet
cao chet » cao chat, cai chet, chai chet
va thanh » gia thanh, ban thanh, va tinh
va hanh » van hanh, va danh, ban hanh
tang xa » trang xa, tang ma, lang xa
van bao » van dao
ky tang » ky nang, ky dang, kho tang
sac ky » cac ky, sai ky
tu sac » tu sach, tu cac, tu san

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky tang xa hoi. hieu ((van bao) or (van ban)) xuc ((va hanh) OR (va thanh)) cao chet triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky tang xa hoi. hieu ((van bao) OR (van ban)) xuc ((va hanh) OR (va thanh)) cao chet triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky tang xa hoi. hieu ((van bao) or (van ban)) xuc ((va hanh) OR (va thanh)) cao chet triet".
• Adding a wildcard symbol may retrieve word variants: tu sac ky tang xa hoi. hieu ((van bao) or (van ban)) xuc ((va hanh) OR (va thanh)) cao chet triet*.
