Perhaps you should try some spelling variations:
va thanh » gia thanh, ban thanh, le thanh
vu sach » vu bach, su sach, vu khach
va tinh » may tinh
hai cua » thai cua, dai cua, hoi cua
hai cuc » tai cuc, thai cua, hai huoc
nang xa » nang x, lang xa, nang ma
cua tre » cua te, cuu tre, cua triet
y nang » ky nang, ly nang, v nang
ve cua » le cua, de cua, te 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: vu sach y nang xa hoi. lieu va ((hai cuc) OR (hai cua)) ((va thanh) OR (va tinh)) ve cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach y nang xa hoi. lieu va ((hai cuc) or (hai cua)) ((va thanh) OR (va tinh)) ve cua tre~".
• Adding a wildcard symbol may retrieve word variants: vu sach y nang xa hoi. lieu va ((hai cuc) or (hai cua)) ((va thanh) OR (va tinh)) ve cua tre*.
