Perhaps you should try some spelling variations:
thien quan » trien quang, lien quan, thien van
hieu quan » hieu qua, lieu quan, lien quan
cua triet » cua viet, su triet, va triet
dao danh » dao doanh, dao dan, dao hanh
am chuc » am thuc, pham chuc, nam thuc
do danh » do dinh, do sanh, dia danh
te cac » tu cac, ve cac, te 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 cac ky nang x ho. ((hieu quan) OR (thien quan)) am chuc ((dao danh) or (do danh)) dai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te cac ky nang x ho. ((hieu quan) OR (thien quan)) am chuc ((dao danh) OR (do danh)) dai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te cac ky nang x ho. ((hieu quan) OR (thien quan)) am chuc ((dao danh) or (do danh)) dai cua triet".
• Adding a wildcard symbol may retrieve word variants: te cac ky nang x ho. ((hieu quan) OR (thien quan)) am chuc ((dao danh) or (do danh)) dai cua triet*.
