Perhaps you should try some spelling variations:
tu sach » thu sach, su sach, te sach
vu khac » vu kham, vu khanh, bui khac
nang xa » nang x, lang xa, nang ma
vu cham » va cham, vu kham, tu cham
ve chat » va chat, van chat
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 sach) OR (vu khac)) y nang xa hoi. hieu ((vu cham) OR (ve chat)) soc va hanh vi cua vat~.
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (vu khac)) y nang xa hoi. hieu ((vu cham) or (ve chat)) soc va hanh vi cua vat*.
