Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
ban thanh » ban hanh, ban hang
van thanh » van tuan
hieu van » hieu va, thien van, lieu va
van cam » van nam, van lam, van cau
tu sach » thu sach, su sach, te sach
ma hoi » mai hoi, xa hoi, ma hoa
y nang » ky nang, ly nang, may nang
v nang » va nang, vu nang, van nang
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 cam xuc ((van thanh) OR (ban 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 cam xuc ((van thanh) OR (ban thanh)) vi cua triet~".
• Adding a wildcard symbol may retrieve word variants: tu sach ((y nang) or (v nang)) ma hoi. hieu van cam xuc ((van thanh) OR (ban thanh)) vi cua triet*.
