Perhaps you should try some spelling variations:
cham truc » cau truc, nham thuc, pham thuc
thien van » thi van
van cham » van chat, van tham, va cham
nang xa » nang x, lang xa, nang ma
sach ty » sach y, sach tu, sach thu
sach ky » sac ky, sach y, sach kem
truc va » thuc va, thuc vat, trung va
dau dau » dan dau, dau da, dau thau
dat dau » dat dai, bat dau, dat cau
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: toc ((sach ky) OR (sach ty)) nang xa hoi. thien van cham truc va ((dau dau) OR (dat dau)) cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((sach ky) or (sach ty)) nang xa hoi. thien van cham truc va ((dau dau) OR (dat dau)) cua tre~".
• Adding a wildcard symbol may retrieve word variants: toc ((sach ky) or (sach ty)) nang xa hoi. thien van cham truc va ((dau dau) OR (dat dau)) cua tre*.
