Perhaps you should try some spelling variations:
thanh de » hanh de, thanh ve, thanh do
va thanh » gia thanh, ban thanh, va tinh
lang xa » lang ha, dang xay, lang van
hieu ve » hieu va, hieu van
sach ky » sac ky, sach ty, sach kem
cac luc » cau luc, cac nuoc, cac cuoc
de cua » le cua, te cua, dieu cua
cua te » cua tu

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