Perhaps you should try some spelling variations:
kho tang » cao tang
va hanh » van hanh, va thanh, va danh
hieu su » hieu sau, tieu su, hieu so
dai moi » doi moi, dai hoi
cua tuc » cua duc, cua thuoc, luat tuc
ky tang » ky nang, ky dang, ky trong
su cam » su nam, su cao, su can
xuc va » duc va, tuc va, luc va
cua tu » cua su, cua cu, cua te
tu sac » tu sach, tu cac, tu san

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ((ky tang) OR (kho tang)) dai moi. hieu su cam xuc va hanh vi ((cua tu) or (cua tuc))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ((ky tang) OR (kho tang)) dai moi. hieu su cam xuc va hanh vi ((cua tu) OR (cua tuc))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ((ky tang) OR (kho tang)) dai moi. hieu su cam xuc va hanh vi ((cua tu) or (cua tuc))*".
