tu sach » thu sach, su sach, te sach
nang xa » nang x, lang xa, nang ma
hanh di » hanh de, hang di, danh di
y nang » ky nang, ly nang, v nang
xuc va » duc va, tuc va, luc va
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 sach y nang xa hoi. ((hieu vien) or (thieu nien)) cam xuc va ((hanh di) OR (hanh vi)) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y nang xa hoi. ((hieu vien) OR (thieu nien)) cam xuc va ((hanh di) OR (hanh vi)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang xa hoi. ((hieu vien) or (thieu nien)) cam xuc va ((hanh di) OR (hanh vi)) cua te".
• Adding a wildcard symbol may retrieve word variants: tu sach y nang xa hoi. ((hieu vien) or (thieu nien)) cam xuc va ((hanh di) OR (hanh vi)) cua te*.
