tu sach » thu sach, su sach, tu cach
hieu ve » hieu va, hieu van
cuu tre » cua tre, cau tren, cau treo
nang xa » nang x, lang xa, nang ma
te sach » toc sach
xuc va » duc va, tuc va, xac va
luc va » duc va, tuc va, loc va
ve cam » ve cham, ve cac, va cam

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) OR (te sach)) ky nang xa hoi. hieu ve cam ((xuc va) or (luc va)) hanh thai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) ky nang xa hoi. hieu ve cam ((xuc va) OR (luc va)) hanh thai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (te sach)) ky nang xa hoi. hieu ve cam ((xuc va) or (luc va)) hanh thai cuu tre".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (te sach)) ky nang xa hoi. hieu ve cam ((xuc va) or (luc va)) hanh thai cuu tre*.
