hieu ve » hieu va, hieu van
tu sai » tu bai, tu san, tu cai
sai ky » sac ky
ve cac » va cac, vien cac
xuc va » duc va, tuc va, luc va
loc va » hoc va, luc va
co cua » con cua, cong cua, cuoi cua

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 nang xa hoi. hieu ve cac ((xuc va) or (loc va)) danh ((ca cua) OR (co cua)) te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sai ky nang xa hoi. hieu ve cac ((xuc va) OR (loc va)) danh ((ca cua) OR (co cua)) te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sai ky nang xa hoi. hieu ve cac ((xuc va) or (loc va)) danh ((ca cua) OR (co cua)) te".
• Adding a wildcard symbol may retrieve word variants: tu sai ky nang xa hoi. hieu ve cac ((xuc va) or (loc va)) danh ((ca cua) OR (co cua)) te*.
