Perhaps you should try some spelling variations:
dang thanh » dong thanh, dang hanh, hoang thanh
thuc dang » thuoc dang, thuc dan, thuc dung
thanh do » thanh de, thanh pho, thanh hoa
bo sach » co sach, hoc sach
ve nhan » de nhan, va nhan, ve phan
cua tre » cua te, cuu tre, cua triet
nang xa » nang x, lang xa, nang ma
te sach » toc sach
ve nha » ke nha
do cua » doi cua, co cua, de 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: ((bo sach) OR (te sach)) ky nang xa hoi. hieu ((ve nhan) OR (ve nha)) thuc dang thanh do cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((bo sach) or (te sach)) ky nang xa hoi. hieu ((ve nhan) OR (ve nha)) thuc dang thanh do cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((bo sach) or (te sach)) ky nang xa hoi. hieu ((ve nhan) OR (ve nha)) thuc dang thanh do cua tre*.
