nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
cac xuc » cam xuc, cac nuoc, chat xuc
va hanh » van hanh, va thanh, va danh
ve cac » va cac, vien cac
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: ((hoc sach) OR (hoc cac)) ky nang xa hoi. hieu ve cac xuc va hanh vi ((cua te) or (ve triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc sach) OR (hoc cac)) ky nang xa hoi. hieu ve cac xuc va hanh vi ((cua te) OR (ve triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc sach) OR (hoc cac)) ky nang xa hoi. hieu ve cac xuc va hanh vi ((cua te) or (ve triet))".
• Adding a wildcard symbol may retrieve word variants: ((hoc sach) OR (hoc cac)) ky nang xa hoi. hieu ve cac xuc va hanh vi ((cua te) or (ve triet))*.
