Perhaps you should try some spelling variations:
hanh tai » thanh tai, hang tai, han tai
dang xay » dang van, van xay
cua tre » cua te, cuu tre, cua triet
ve cham » va cham, ve chat, vu cham
tai cua » thai cua, tai cuc, tri cua
coc ban » co ban, cac ban, hoc ban
soc ban » hoc ban, so ban, soc ba
hieu ve » hieu va, hieu van
mang xa » lang xa, mang may, mang cua
sac ky » cac ky, sai ky
tu sac » tu sach, tu cac, tu san

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

• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky ((mang xa) OR (dang xay)) hoi. hieu ve cham ((soc ban) OR (coc ban)) hanh tai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky ((mang xa) or (dang xay)) hoi. hieu ve cham ((soc ban) OR (coc ban)) hanh tai cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky ((mang xa) or (dang xay)) hoi. hieu ve cham ((soc ban) OR (coc ban)) hanh tai cua tre*.
