Perhaps you should try some spelling variations:
thien van » thi van
hieu van » hieu va, lieu va, hieu ve
hang tai » hang va, dung tai
so sach » so sanh, bo sach, co sach
xuc van » duc van, luc van, vuc van
hanh va » hang va, hanh vi
cau xuc » cam xuc, cau luc, cau truc
sach ty » sach y, sach tu, sach thu
xang xa » lang xa, mang xa, ang xa
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: so sach ty xang xa hoi. ((hieu van) OR (thien van)) cau xuc van ((hang tai) or (hanh va)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ty xang xa hoi. ((hieu van) OR (thien van)) cau xuc van ((hang tai) OR (hanh va)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ty xang xa hoi. ((hieu van) OR (thien van)) cau xuc van ((hang tai) or (hanh va)) cua tre*".
