Perhaps you should try some spelling variations:
sach thue » sach thu, sach thieu, sach tham
thue nang » thien nang, thuat nang, thi nang
van hanh » van thanh, ban hanh, van anh
te sach » toc sach
nang xa » nang x, lang xa, nang ma
xuc van » duc van, luc van, vuc van
cua cau » cua chu, cua cay, cua can
ve 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 thue nang xa hoi. hieu ((ve cac) or (va cac)) xuc van hanh vi ((cua cau) OR (cua cac))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach thue nang xa hoi. hieu ((ve cac) OR (va cac)) xuc van hanh vi ((cua cau) OR (cua cac)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach thue nang xa hoi. hieu ((ve cac) or (va cac)) xuc van hanh vi ((cua cau) OR (cua cac))".
• Adding a wildcard symbol may retrieve word variants: te sach thue nang xa hoi. hieu ((ve cac) or (va cac)) xuc van hanh vi ((cua cau) OR (cua cac))*.
