Perhaps you should try some spelling variations:
cuc triet » cua triet, su triet, cac trieu
tham luu » tam luu, thanh luu, phap luu
cham cuu » cap cuu, chat cua
ban dung » van dung, tan dung, lan dung
dan dung » van dung, tin dung, ap dung
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
hieu va » lieu va, hieu qua

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu cac ky lang xa hoi. hieu va ((tham luu) or (cham cuu)) ((ban dung) OR (dan dung)) tai cuc triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ky lang xa hoi. hieu va ((tham luu) OR (cham cuu)) ((ban dung) OR (dan dung)) tai cuc triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky lang xa hoi. hieu va ((tham luu) or (cham cuu)) ((ban dung) OR (dan dung)) tai cuc triet*".
