Perhaps you should try some spelling variations:
van triet » van thiet, van trieu, hanh triet
va triet » va thiet, va trien, ve triet
van hanh » van thanh, ban hanh, van anh
vu cham » va cham, vu kham, tu cham
tuc van » thuc van, truc van, tuc va
hanh vu » hanh vi, hanh va, hanh tu
dinh xa » dinh ba, dinh va, dinh xu
su sach » so sach, vu sach
ve cam » ve cham, ve cac, va cam
y dinh » my dinh, _ dinh, o dinh

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 dinh xa hoi. hieu ((ve cam) or (vu cham)) tuc van hanh vu ((van triet) OR (va triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y dinh xa hoi. hieu ((ve cam) OR (vu cham)) tuc van hanh vu ((van triet) OR (va triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y dinh xa hoi. hieu ((ve cam) or (vu cham)) tuc van hanh vu ((van triet) OR (va triet))*".
