Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
van hanh » van thanh, ban hanh, van anh
te sach » toc sach
nang xa » nang x, nang ma, mang xa
lang xa » lang ha, dang xay, lang van
qua cam » qua cham, qua cac, qua ca
xuc van » duc van, luc van, vuc van
su tien » su kien, su hien, tu tieng

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sach y ((nang xa) OR (lang xa)) hoi. hieu qua cam xuc van hanh vi ((cua triet) or (su tien))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y ((nang xa) OR (lang xa)) hoi. hieu qua cam xuc van hanh vi ((cua triet) OR (su tien)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y ((nang xa) OR (lang xa)) hoi. hieu qua cam xuc van hanh vi ((cua triet) or (su tien))".
• Adding a wildcard symbol may retrieve word variants: te sach y ((nang xa) OR (lang xa)) hoi. hieu qua cam xuc van hanh vi ((cua triet) or (su tien))*.
