Perhaps you should try some spelling variations:
va trien » va truyen, va thiet, va tuyen
va triet » va thiet, ve triet, cua triet
van hanh » van thanh, ban hanh, van anh
cham xuc » cam xuc, chat xuc, cham soc
lang xa » lang ha, dang xay, lang van
hieu ve » hieu va, hieu van
ve cham » va cham, ve chat, vu cham
xuc van » duc van, luc van, vuc van
hanh va » hang va, hanh vi
nang xa » nang x, nang ma, mang xa
su sach » so sach, vu sach

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sach y ((nang xa) or (lang xa)) hoi. hieu ve cham xuc van hanh va ((va triet) OR (va trien))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y ((nang xa) OR (lang xa)) hoi. hieu ve cham xuc van hanh va ((va triet) OR (va trien))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y ((nang xa) or (lang xa)) hoi. hieu ve cham xuc van hanh va ((va triet) OR (va trien))*".
