Perhaps you should try some spelling variations:
thanh ve » hanh ve, thanh va, thanh vien
lang xa » lang ha, dang xay, lang van
hieu ve » hieu va, hieu van
dau gia » danh gia, cau giay, mau giao
cua tre » cua te, cuu tre, cua triet
sac ky » cac ky, sai ky
ve cac » va cac, vien cac
du gia » duc gia, vu gia, de gia
ve cua » le cua, de cua, te cua

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: su ((sach y) or (sac ky)) lang xa hoi. hieu ve cac ((du gia) OR (dau gia)) thanh ve cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach y) OR (sac ky)) lang xa hoi. hieu ve cac ((du gia) OR (dau gia)) thanh ve cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach y) or (sac ky)) lang xa hoi. hieu ve cac ((du gia) OR (dau gia)) thanh ve cua tre*".
