Perhaps you should try some spelling variations:
sach ky » sac ky, sach y, sach ty
hanh de » hanh ve, hanh kem
hanh di » hanh vi, hang di, danh di
thuc va » thuc vat, thuc dan, thuc day
tu sach » thu sach, su sach, te sach
lang xa » lang ha, dang xay, lang van
ky lang » ky nang, ky dang, ky tang
cua tre » cua te, cuu tre, cua triet
va lap » va dap
va lam » van lam

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 ky lang xa hoi. lieu ((va lam) or (va lap)) thuc va ((hanh di) OR (hanh de)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky lang xa hoi. lieu ((va lam) OR (va lap)) thuc va ((hanh di) OR (hanh de)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky lang xa hoi. lieu ((va lam) or (va lap)) thuc va ((hanh di) OR (hanh de)) cua tre".
• Adding a wildcard symbol may retrieve word variants: tu sach ky lang xa hoi. lieu ((va lam) or (va lap)) thuc va ((hanh di) OR (hanh de)) cua tre*.
