Perhaps you should try some spelling variations:
thanh de » hanh de, thanh ve, thanh do
va thanh » gia thanh, ban thanh, va tinh
su sach » vu sach
cuu tre » cua tre, cau tren, cau treo
dang xa » dang xay, lang xa, dang ha
ky dang » ky nang, ky danh
so sach » so sanh, bo sach, co sach
ve cac » va cac, vien cac
luc va » duc va, tuc va, loc va
de cuu » de cua
ve cau » ke cau, va cau, le cau

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: ((su sach) OR (so sach)) ky dang xa hoi. hieu ((ve cau) OR (ve cac)) luc va thanh de cuu tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (so sach)) ky dang xa hoi. hieu ((ve cau) OR (ve cac)) luc va thanh de cuu tre~".
• Adding a wildcard symbol may retrieve word variants: ((su sach) or (so sach)) ky dang xa hoi. hieu ((ve cau) OR (ve cac)) luc va thanh de cuu tre*.
