Perhaps you should try some spelling variations:
van hanh » van thanh, van anh, van ban
ban hanh » ban hang
vai cua » dai cua, hai cua, lai cua
dang xa » dang xay, lang xa, dang ha
hieu ve » hieu va, hieu van
sach ky » sac ky, sach ty, sach kem
cac xuc » cam xuc, cac nuoc, chat xuc
ve cac » va cac, vien cac
cua te » cua tu

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach ky) OR (sach y)) dang xa hoi. hieu ve cac xuc ((van hanh) or (ban hanh)) vai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (sach y)) dang xa hoi. hieu ve cac xuc ((van hanh) OR (ban hanh)) vai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) OR (sach y)) dang xa hoi. hieu ve cac xuc ((van hanh) or (ban hanh)) vai cua te*".
