Perhaps you should try some spelling variations:
thanh duy » thanh huy, khanh duy, thanh thuy
van thanh » ban thanh, van tuan
vien cac » vien bach, vien dai, vien da
so sach » bo sach, co sach, hoc sach
duy cua » day cua, dung cua
so sanh » do sanh
xang xa » lang xa, mang xa, ang xa
xuc van » duc van, luc van, vuc van
cua te » cua tu
ve cac » va cac

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((so sach) OR (so sanh)) ty xang xa hoi. hieu ((ve cac) or (vien cac)) xuc van thanh duy cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((so sach) OR (so sanh)) ty xang xa hoi. hieu ((ve cac) OR (vien cac)) xuc van thanh duy cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((so sach) OR (so sanh)) ty xang xa hoi. hieu ((ve cac) or (vien cac)) xuc van thanh duy cua te*".
