Perhaps you should try some spelling variations:
cua viet » ca viet, hoa viet, cua vat
tu cach » tu cac
su sach » so sach, vu sach
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
ve cham » va cham, ve chat, vu cham
va hanh » van hanh, va thanh, va danh
y nang » ky nang, ly nang, v nang
soc va » hoc va, loc va, doc va
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 cach) OR (su sach)) y nang xa hoi. hieu ve cham soc va hanh vi cua viet~.
• Adding a wildcard symbol may retrieve word variants: ((tu cach) or (su sach)) y nang xa hoi. hieu ve cham soc va hanh vi cua viet*.
