lap hai » lap tai, lap lai, lanh hai
hieu ve » hieu va, hieu van
vi cua » vai cua, di cua
xuc va » tuc va, luc va, xac va
tu sai » tu bai, tu san, tu cai
ve cac » va cac, vien cac
sai ky » sac ky
cua te » cua tu

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sai ky dang ((lap hai) OR (lap hoat)). hieu ve cac ((xuc va) or (duc va)) hanh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sai ky dang ((lap hai) OR (lap hoat)). hieu ve cac ((xuc va) OR (duc va)) hanh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sai ky dang ((lap hai) OR (lap hoat)). hieu ve cac ((xuc va) or (duc va)) hanh vi cua te".
• Adding a wildcard symbol may retrieve word variants: tu sai ky dang ((lap hai) OR (lap hoat)). hieu ve cac ((xuc va) or (duc va)) hanh vi cua te*.
