Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thanh vai » thanh hai, thanh van, thanh tai
ban thanh » ban hanh, ban hang
cac duc » cac du, cao duc, cac dac
cua tre » cua te, cuu tre, dua tren
duc ban » duc tan, duc van, dua ban
te sach » toc sach
sach ky » sac ky, sach y, sach ty
hieu ve » hieu va, hieu van
ma hoi » mai hoi, xa hoi, me hoi
ve cac » va cac, vien cac

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky nang ((ma hoi) OR (ma hoa)). hieu ve cac duc ban thanh vai ((cua tre) or (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang ((ma hoi) OR (ma hoa)). hieu ve cac duc ban thanh vai ((cua tre) OR (cua triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang ((ma hoi) OR (ma hoa)). hieu ve cac duc ban thanh vai ((cua tre) or (cua triet))*".
