Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hanh vai » hanh va, hanh tai, hanh van
cau tuc » cau truc, cau tu, cau phuc
cau luc » cau truc, cau phuc
tu sach » thu sach, su sach, te sach
nang ma » tang ma, sang ma, nang cao
hieu va » lieu va, hieu qua
y nang » ky nang, ly nang, v nang
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 sach y nang ma hoi. hieu va ((cau tuc) OR (cau luc)) xa ((hanh vai) or (hanh vi)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y nang ma hoi. hieu va ((cau tuc) OR (cau luc)) xa ((hanh vai) OR (hanh vi)) cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang ma hoi. hieu va ((cau tuc) OR (cau luc)) xa ((hanh vai) or (hanh vi)) cua triet*".
