Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
te sach » toc sach
sach ky » sac ky, sach y, sach ty
ky tang » ky nang, ky dang, kho tang
tang xa » trang xa, tang ma, lang xa
van cam » van nam, van lam, van cau
xuc ban » cuc ban, quoc ban, xuat ban
duc ban » duc tan, duc van, dua ban
cua tre » cua te, cua triet, dua tren
cuu tre » cau tren, cau treo

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