Perhaps you should try some spelling variations:
tuan tai » toan tai, quan tai, tan tai
dang xay » dang van, van xay
cua tre » cua te, cuu tre, cua triet
luc van » luoc van, luu van, duc van
nang xa » nang x, lang xa, nang ma
tai cua » thai cua, tai cuc, tri cua
hieu ve » hieu va, hieu van
xuc van » duc van, vuc van, xuc ban
su sac » su sach, su cac, su xac
sac ky » cac ky, sai ky
ve cac » va cac, vien cac

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: su sac ky ((nang xa) OR (dang xay)) hoi. hieu ve cac ((xuc van) OR (luc van)) tuan tai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky ((nang xa) or (dang xay)) hoi. hieu ve cac ((xuc van) OR (luc van)) tuan tai cua tre~".
• Adding a wildcard symbol may retrieve word variants: su sac ky ((nang xa) or (dang xay)) hoi. hieu ve cac ((xuc van) OR (luc van)) tuan tai cua tre*.
