Perhaps you should try some spelling variations:
cham tuc » nham thuc, pham thuc, tham thuc
hang vi » hang va, hang di, khang voi
tuc van » thuc van, truc van, tuc va
sach ky » sac ky, sach y, sach kem
va cham » va chat, va tham
hieu va » lieu va, hieu qua
nang xa » nang x, lang xa, nang ma
sach ty » sach y, sach tu, sach thu
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: te ((sach ky) OR (sach ty)) nang xa hoi. hieu va cham tuc van ((hang vi) OR (hanh vi)) cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) OR (sach ty)) nang xa hoi. hieu va cham tuc van ((hang vi) or (hanh vi)) cua tre~".
• Adding a wildcard symbol may retrieve word variants: te ((sach ky) OR (sach ty)) nang xa hoi. hieu va cham tuc van ((hang vi) or (hanh vi)) cua tre*.
