Perhaps you should try some spelling variations:
hanh vai » hanh vi, hanh va, hanh tai
su sach » so sach, vu sach
sach ty » sach y, sach tu, sach thu
xang xa » lang xa, mang xa, ang xa
thi van » thi lan, thi hanh, thi nang
thuc va » thuc vat, thuc dan, thuc day
cuu tre » cau tren, cau treo
cua tre » cua te, cua triet, dua tren
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: su sach ty xang xa hoi. thi van nam ((xuc va) or (thuc va)) hanh vai ((cuu tre) OR (cua tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty xang xa hoi. thi van nam ((xuc va) OR (thuc va)) hanh vai ((cuu tre) OR (cua tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty xang xa hoi. thi van nam ((xuc va) or (thuc va)) hanh vai ((cuu tre) OR (cua tre))".
• Adding a wildcard symbol may retrieve word variants: su sach ty xang xa hoi. thi van nam ((xuc va) or (thuc va)) hanh vai ((cuu tre) OR (cua tre))*.
