Perhaps you should try some spelling variations:
dang xay » dang van, van xay
van quan » van ban
xuc van » duc van, luc van, vuc van
cac xuc » cam xuc, cac nuoc, chat xuc
hieu ve » hieu va, hieu van
cua tre » cua te, cuu tre, cua triet
nang ma » tang ma, sang ma, nang cao
nang xa » nang x, lang xa, mang xa
sac ky » cac ky, sai ky
ve cac » va cac, vien cac
su sac » su sach, su cac, su xac

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