Perhaps you should try some spelling variations:
toc sach » hoc sach, doc sach, thuoc sach
xang cho » sang cho, hang cho, tang cho
sach tu » sach thu, cach tu, sach ty
tu xang » ty xang, tu lang, tu quang
cho hoc » co hoc, khoa hoc
hieu ve » hieu va, hieu van
xuc van » luc van, vuc van, xuc ban
duc van » duc va, duc tan, duc manh
cua cau » cua cac, cua cay, cua can
cua chu » sua chua
ve cac » va cac, vien cac

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: toc sach tu xang cho hoc. hieu ve cac ((xuc van) OR (duc van)) hanh vi ((cua cau) or (cua chu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach tu xang cho hoc. hieu ve cac ((xuc van) OR (duc van)) hanh vi ((cua cau) OR (cua chu))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach tu xang cho hoc. hieu ve cac ((xuc van) OR (duc van)) hanh vi ((cua cau) or (cua chu))*".
