Perhaps you should try some spelling variations:
van thanh » ban thanh, van tuan
cua triet » cua viet, su triet, va triet
hieu van » hieu va, thien van, hieu ve
thanh vi » hanh vi, thanh va, thanh ve
tu sach » thu sach, su sach, te sach
xuc van » duc van, luc van, xuc ban
y nang » ky nang, ly nang, may nang
v nang » va nang, vu nang, van nang
ma hoi » mai hoi, xa hoi, ma hoa
vi cua » vai cua, di cua

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) OR (lieu va)) cam xuc van thanh vi cua 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) OR (lieu va)) cam xuc van thanh vi cua triet~".
• Adding a wildcard symbol may retrieve word variants: tu sach ((y nang) or (v nang)) ma hoi. ((hieu van) OR (lieu va)) cam xuc van thanh vi cua triet*.
