Perhaps you should try some spelling variations:
ve triet » va trien
cham xuc » cam xuc, chat xuc, cham soc
su triet » su tien
su viet » so viet
tu sach » thu sach, su sach, te sach
ve cham » va cham, ve chat, vu cham
hieu ve » hieu va, hieu van
nang xa » nang x, lang xa, nang ma
va hanh » van hanh, va thanh, va danh
xuc va » duc va, tuc va, luc va
y nang » ky nang, ly nang, v nang

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 ve cham xuc va hanh vi ((((su triet) OR (su viet))) or (ve triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y nang xa hoi. hieu ve cham xuc va hanh vi ((((su triet) OR (su viet))) OR (ve triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang xa hoi. hieu ve cham xuc va hanh vi ((((su triet) OR (su viet))) or (ve triet))".
• Adding a wildcard symbol may retrieve word variants: tu sach y nang xa hoi. hieu ve cham xuc va hanh vi ((((su triet) OR (su viet))) or (ve triet))*.
