Perhaps you should try some spelling variations:
xang cho » sang cho, hang cho, tang cho
te sach » toc sach
sach tu » sach thu, cach tu, sach ty
hieu ve » hieu va, hieu van
xuc van » luc van, vuc van, xuc ban
duc van » duc va, duc tan, duc manh
ve cac » va cac, vien cac
vi cua » vai cua, di cua

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 tu ((xang cho) or (dung cho)) hoc. hieu ve cac ((xuc van) OR (duc van)) hanh vi cua cac~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach tu ((xang cho) OR (dung cho)) hoc. hieu ve cac ((xuc van) OR (duc van)) hanh vi cua cac*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach tu ((xang cho) or (dung cho)) hoc. hieu ve cac ((xuc van) OR (duc van)) hanh vi cua cac*".
