Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
qua tham » qua cham, qua thanh, quan pham
qua than » qua thanh, qua phan, qua tan
hanh vai » hanh vi, hanh tai, hanh van
nang ma » tang ma, sang ma, nang cao
luu ban » luu bang, luu van, luu dan
hanh va » hang va, hanh vi
ma hoi » mai hoi, xa hoi, ma hoa

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 nang ma hoi. hieu ((qua tham) OR (qua than)) luu ban ((hanh vai) or (hanh va)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ky nang ma hoi. hieu ((qua tham) OR (qua than)) luu ban ((hanh vai) OR (hanh va)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky nang ma hoi. hieu ((qua tham) OR (qua than)) luu ban ((hanh vai) or (hanh va)) cua triet".
• Adding a wildcard symbol may retrieve word variants: tu cac ky nang ma hoi. hieu ((qua tham) OR (qua than)) luu ban ((hanh vai) or (hanh va)) cua triet*.
