Perhaps you should try some spelling variations:
ve triet » va trien, su triet
chat xuc » chat huu, cam xuc, chao xu
cao hoi » cau hoi, co hoi, cao hoc
hieu va » lieu va, hieu qua
va chat » van chat, va phat, cao chat
va hang » van hang, va lang, va hanh
va nang » van nang, da nang, cam nang
dien ve » dien va, dien he, dien vu
su dai » si dai, su tai, su hai

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((su dai) OR (sau dai)) ky nang cao hoi. hieu va chat xuc ((va hang) or (va nang)) dien ve triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su dai) OR (sau dai)) ky nang cao hoi. hieu va chat xuc ((va hang) OR (va nang)) dien ve triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su dai) OR (sau dai)) ky nang cao hoi. hieu va chat xuc ((va hang) or (va nang)) dien ve triet".
• Adding a wildcard symbol may retrieve word variants: ((su dai) OR (sau dai)) ky nang cao hoi. hieu va chat xuc ((va hang) or (va nang)) dien ve triet*.
