Perhaps you should try some spelling variations:
hieu tuc » hieu thuc, hieu luc, hieu thuoc
cham xuc » cam xuc, chat xuc, cham soc
dang van » hoang van, hang va
tu sach » thu sach, su sach, tu cach
te sach » toc sach
nang xa » nang x, lang xa, nang ma
hieu tu » chieu tu, hien tu, lieu tu
va dang » van dang, va nang, va lang
xuc va » duc va, tuc va, luc va
hoa » khoa

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

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