Perhaps you should try some spelling variations:
van thanh » ban thanh, van tuan
su triet » su viet, su tien, ve triet
van quan » van ban
thanh ve » hanh ve, thanh va, thanh vien
thanh vi » hanh vi, thanh va, nhanh vi
nang xa » nang x, lang xa, nang ma
tu sach » thu sach, su sach, te sach
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: tu sach y nang xa hoi. hieu ((van thanh) or (van quan)) xuc va ((thanh vi) OR (thanh ve)) su triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y nang xa hoi. hieu ((van thanh) OR (van quan)) xuc va ((thanh vi) OR (thanh ve)) su triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang xa hoi. hieu ((van thanh) or (van quan)) xuc va ((thanh vi) OR (thanh ve)) su triet".
• Adding a wildcard symbol may retrieve word variants: tu sach y nang xa hoi. hieu ((van thanh) or (van quan)) xuc va ((thanh vi) OR (thanh ve)) su triet*.
