Perhaps you should try some spelling variations:
hanh vai » hanh vi, hanh va, hanh tai
dang xay » dang van, van xay
hieu van » hieu va, thien van, lieu va
te sach » toc sach
cuc ban » cua ban, cuu ban, duc ban
vai cua » dai cua, hai cua, lai cua
cac ban » cac dan, cac van, can ban
van cam » van nam, van lam, van cau
lang xa » lang ha, lang van
cua tre » cua te, cuu tre, cua triet

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

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