Perhaps you should try some spelling variations:
hanh vai » hanh vi, hanh va, hanh tai
thuc dan » thuc hanh, hoc dan, thuc vat
sach ty » sach tu, sach thu, xach tay
vai cuu » vai cua
van cau » van dau, van hau, van chat
thi van » thi lan, thi hanh, thi nang
nang ma » tang ma, sang ma, nang cao
cuu tre » cua tre, cau tren, cau treo
ma hoi » mai hoi, xa hoi, ma hoa
xuc va » duc va, tuc va, luc va

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 ty) OR (sach y)) nang ma hoi. thi van cau ((xuc va) or (thuc dan)) hanh vai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ty) OR (sach y)) nang ma hoi. thi van cau ((xuc va) OR (thuc dan)) hanh vai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ty) OR (sach y)) nang ma hoi. thi van cau ((xuc va) or (thuc dan)) hanh vai cuu tre".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ty) OR (sach y)) nang ma hoi. thi van cau ((xuc va) or (thuc dan)) hanh vai cuu tre*.
