hieu ve » hieu va, hieu van
cua tre » cua te, cuu tre, cua triet
nang xa » nang x, lang xa, nang ma
sac ky » cac ky, sai ky
xuc va » duc va, luc va, xac va
tuc va » thuc va, truc va, tuc xa

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