Perhaps you should try some spelling variations:
thanh vi » hanh vi, thanh va, thanh ve
cuu thuc » cuu tac
te sach » toc sach
sach ty » sach y, sach tu, sach thu
xang xa » lang xa, mang xa, dang xay
hieu va » lieu va, hieu qua
va tham » van tham, va cham, va thanh
ang xa » lang xa, mang xa, dang xay
xuc va » tuc va, luc va, xac va
vi cuu » vi luu, vinh cuu

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: te sach ty ((xang xa) OR (ang xa)) hoi. hieu va tham ((xuc va) or (duc va)) thanh vi cuu thuc~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty ((xang xa) OR (ang xa)) hoi. hieu va tham ((xuc va) OR (duc va)) thanh vi cuu thuc.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty ((xang xa) OR (ang xa)) hoi. hieu va tham ((xuc va) or (duc va)) thanh vi cuu thuc".
• Adding a wildcard symbol may retrieve word variants: te sach ty ((xang xa) OR (ang xa)) hoi. hieu va tham ((xuc va) or (duc va)) thanh vi cuu thuc*.
