Perhaps you should try some spelling variations:
ve triet » va trien, su triet
va hanh » van hanh, va thanh, va danh
te sach » toc sach
ve cai » va cai, ve tai, ve cau
y nang » ky nang, ly nang, v nang
va cao » va cac, va co, va dao
luc va » duc va, tuc va, loc va
ve cac » va cac, vien cac
x hoi » xa hoi, o hoi, x ho
vi ve » va ve, gi ve, ve ve

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 x hoi. hieu ((((ve cai) or (ve cac))) or (va cao)) luc va hanh vi ve triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang x hoi. hieu ((((ve cai) OR (ve cac))) OR (va cao)) luc va hanh vi ve triet.
• Adding a wildcard symbol may retrieve word variants: te sach y nang x hoi. hieu ((((ve cai) or (ve cac))) or (va cao)) luc va hanh vi ve triet*.
