Perhaps you should try some spelling variations:
dang xay » dang van, van xay
cua tre » cua te, cuu tre, cua triet
tai cua » thai cua, tai cuc, tri cua
ban tai » van tai, han tai, ban thi
vuc van » duc van, luc van, thuc van
xuc van » duc van, luc van, xuc ban
hieu ve » hieu va, hieu van
nang xa » nang x, lang xa, nang ma
ve cac » va cac, vien cac
sai ky » sac ky
su sai » su tai, su hai, su dai

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