Perhaps you should try some spelling variations:
ban thanh » ban hanh, ban hang
thien van » thi van
dau truc » cau truc, dai truc, doan truc
va thanh » gia thanh, va tinh, le thanh
vai cua » dai cua, hai cua, lai cua
van dau » van dao, phan dau
sach ky » sac ky, sach ty, sach kem
nang xa » nang x, lang xa, nang ma
cua tre » cua te, cuu tre, cua triet

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 ((sach ky) OR (sach y)) nang xa hoi. thien van dau truc ((va thanh) OR (ban thanh)) vai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) or (sach y)) nang xa hoi. thien van dau truc ((va thanh) OR (ban thanh)) vai cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ky) or (sach y)) nang xa hoi. thien van dau truc ((va thanh) OR (ban thanh)) vai cua tre*.
