nang xa » nang x, lang xa, nang ma
van dau » van dao, phan dau
danh vi » hanh vi, danh di, danh va
dinh vi » dinh ve, dinh viet, dinh tri
xu tren » tu tren, cu tren, xa tren
y nang » ky nang, ly nang, v nang
xuc va » duc va, tuc va, luc va

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sach y nang xa hoi. hieu ((van nam) or (van dau)) xuc va ((danh vi) OR (dinh vi)) xu tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang xa hoi. hieu ((van nam) OR (van dau)) xuc va ((danh vi) OR (dinh vi)) xu tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang xa hoi. hieu ((van nam) or (van dau)) xuc va ((danh vi) OR (dinh vi)) xu tren".
• Adding a wildcard symbol may retrieve word variants: te sach y nang xa hoi. hieu ((van nam) or (van dau)) xuc va ((danh vi) OR (dinh vi)) xu tren*.
