Perhaps you should try some spelling variations:
toc sach » hoc sach, doc sach, thuoc sach
xang cho » sang cho, hang cho, tang cho
hanh vai » hanh vi, hanh va, hanh tai
van hanh » van thanh, ban hanh, van anh
xuc van » duc van, luc van, vuc van
cua cau » cua chu, cua cay, cua can
hieu ve » hieu va, hieu van
cac xuc » cam xuc, cac nuoc, chat xuc
cho hoc » co hoc, khoa hoc
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: ((te sach) OR (toc sach)) ty xang cho hoc. hieu ve cac xuc van hanh vai ((cua cau) or (cua cac))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (toc sach)) ty xang cho hoc. hieu ve cac xuc van hanh vai ((cua cau) OR (cua cac))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) OR (toc sach)) ty xang cho hoc. hieu ve cac xuc van hanh vai ((cua cau) or (cua cac))*".
