Perhaps you should try some spelling variations:
thien van » thi van
hieu van » hieu va, lieu va, hieu ve
te sach » toc sach
sach ky » sac ky, sach y, sach ty
ky dang » ky nang, ky danh
dang ma » dang mau, dang mam, dang mat
va hanh » van hanh, va thanh, va danh
cua tre » cuu tre, cua triet, dua tren
ma hoi » mai hoi, xa hoi, ma hoa
xuc va » duc va, tuc va, luc va
cua te » cua tu

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 dang ma hoi. ((hieu van) OR (thien van)) cam xuc va hanh vi ((cua te) or (cua tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky dang ma hoi. ((hieu van) OR (thien van)) cam xuc va hanh vi ((cua te) OR (cua tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky dang ma hoi. ((hieu van) OR (thien van)) cam xuc va hanh vi ((cua te) or (cua tre))".
• Adding a wildcard symbol may retrieve word variants: te sach ky dang ma hoi. ((hieu van) OR (thien van)) cam xuc va hanh vi ((cua te) or (cua tre))*.
