cua tre » cua te, cuu tre, cua triet
hieu ve » hieu va, hieu van
nang ma » tang ma, sang ma, nang cao
sai ky » sac ky
xuc va » duc va, tuc va, luc va
ma hoi » mai hoi, xa hoi, ma hoa
te sai » te tai, te bai, te lai

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

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