Perhaps you should try some spelling variations:
te sach » toc sach
hanh di » hanh vi, hanh de, hang di
va hanh » van hanh, va thanh, va danh
cau tuc » cau truc, cau tu, cau luc
hieu va » lieu va, hieu qua
sach ty » sach y, sach tu, sach thu
cua tre » cua te, cuu tre, cua triet
hieu ve » hieu van
lang xa » lang ha, dang xay, lang van
nang xa » nang x, nang ma, mang xa
tuc va » thuc va, truc va, tuc xa
di cua » dai cua, doi cua, de cua

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 ty ((nang xa) OR (lang xa)) hoi. ((hieu ve) OR (hieu va)) cau tuc va hanh di cua tre~.
• Adding a wildcard symbol may retrieve word variants: te sach ty ((nang xa) or (lang xa)) hoi. ((hieu ve) or (hieu va)) cau tuc va hanh di cua tre*.
