Perhaps you should try some spelling variations:
cua viet » ca viet, hoa viet, cua vat
va hanh » van hanh, va thanh, va danh
ve chat » va chat, van chat
tu sach » thu sach, su sach, te sach
vu khac » vu kham, vu khanh, bui khac
ve cham » va cham, vu cham, ve chim
y nang » ky nang, ly nang, v nang
soc va » hoc va, loc va, doc va
vi cua » vai cua, di cua
x hoi » xa hoi, o hoi, x ho

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) OR (vu khac)) y nang x hoi. hieu ((ve cham) OR (ve chat)) soc va hanh vi cua viet~.
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (vu khac)) y nang x hoi. hieu ((ve cham) or (ve chat)) soc va hanh vi cua viet*.
