te sach » toc sach
sach ty » sach y, sach tu, sach thu
xang xa » lang xa, mang xa, ang xa
hieu ve » hieu va
xuc ban » duc ban, cuc ban, quoc ban
vuc van » duc van, luc van, thuc van
tai nha » tai ha, tai ngan, tai khoa

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 ty xang xa hoi. ((hieu ve) OR (hieu van)) cam ((xuc ban) or (vuc van)) hanh tai nha nuoc~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty xang xa hoi. ((hieu ve) OR (hieu van)) cam ((xuc ban) OR (vuc van)) hanh tai nha nuoc.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty xang xa hoi. ((hieu ve) OR (hieu van)) cam ((xuc ban) or (vuc van)) hanh tai nha nuoc".
• Adding a wildcard symbol may retrieve word variants: te sach ty xang xa hoi. ((hieu ve) OR (hieu van)) cam ((xuc ban) or (vuc van)) hanh tai nha nuoc*.
