Perhaps you should try some spelling variations:
cua triet » cua viet, su triet
va triet » va thiet, va trien, ve triet
van hanh » van thanh, ban hanh, van anh
tuc van » thuc van, truc van, tuc va
ve cham » va cham, ve chat, vu cham
sac ky » cac ky, sai ky
ve cam » ve cac, va cam, ve cai
su sac » su sach, su cac, su xac
x hoi » xa hoi, o hoi, x ho

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

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