Perhaps you should try some spelling variations:
va triet » va thiet, va trien, ve triet
thanh vi » hanh vi, thanh va, thanh ve
hieu van » hieu va, thien van, lieu va
van cam » van nam, van lam, van cau
xuc van » duc van, luc van, thuc van
xuc ban » duc ban, cuc ban, quoc ban
tu sach » thu sach, su sach, te sach
ma hoi » mai hoi, xa hoi, ma hoa
v nang » va nang, vu nang, van nang
y nang » ky nang, ly nang, may nang
vi va » vi van, vai va, vu va

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

• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((y nang) OR (v nang)) ma hoi. hieu van cam ((xuc van) OR (xuc ban)) thanh vi va triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((y nang) or (v nang)) ma hoi. hieu van cam ((xuc van) OR (xuc ban)) thanh vi va triet~".
• Adding a wildcard symbol may retrieve word variants: tu sach ((y nang) or (v nang)) ma hoi. hieu van cam ((xuc van) OR (xuc ban)) thanh vi va triet*.
