Perhaps you should try some spelling variations:
hoc sach » hoc sinh, hoc cac, hoc anh
cao xuc » cam xuc, cao duc, cao suc
nang xa » lang xa, nang ma, mang xa
hanh di » hanh vi, hanh de, hang di
va hanh » van hanh, va thanh, va danh
hieu va » hieu qua
sach ty » sach y, sach tu, sach thu
di cua » dai cua, doi cua, de cua
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.

• If you are trying to use Boolean operators, they must be ALL CAPS: hoc sach ty ((nang xa) OR (nang x)) hoi. ((hieu va) OR (lieu va)) cao xuc va hanh di cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc sach ty ((nang xa) or (nang x)) hoi. ((hieu va) OR (lieu va)) cao xuc va hanh di cua te~".
• Adding a wildcard symbol may retrieve word variants: hoc sach ty ((nang xa) or (nang x)) hoi. ((hieu va) OR (lieu va)) cao xuc va hanh di cua te*.
