Perhaps you should try some spelling variations:
nhan luc » nang luc
ban hanh » ban hang
va triet » va thiet, va trien, cua triet
ve triet » va trien
su triet » su viet, su tien
thu sac » thu sach, thu san, thu xac
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
va nhan » van nhan, ca nhan, va phan
luc ban » duc ban, cuc ban, luc bat
sac ky » cac ky, sai ky

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

• Performing a fuzzy search may retrieve terms with similar spellings: thu sac ky nang xa hoi. hieu va nhan luc ban hanh vi ((((va triet) OR (ve triet))) or (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sac ky nang xa hoi. hieu va nhan luc ban hanh vi ((((va triet) OR (ve triet))) OR (su triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sac ky nang xa hoi. hieu va nhan luc ban hanh vi ((((va triet) OR (ve triet))) or (su triet))".
• Adding a wildcard symbol may retrieve word variants: thu sac ky nang xa hoi. hieu va nhan luc ban hanh vi ((((va triet) OR (ve triet))) or (su triet))*.
