Perhaps you should try some spelling variations:
vien cac » vien bach, vien dai, vien da
so sanh » do sanh
xang xa » lang xa, mang xa, dang xay
hanh du » hanh dua, hanh tu, hanh de
va hanh » van hanh, va thanh, va danh
sanh ty » sach ty, canh tay
du cua » duy cua, dau cua, dum cua
xuc va » duc va, tuc va, luc va
cua te » cua tu
ve cac » va cac
ang xa » lang xa, mang xa, dang xay

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

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