minh tri » dinh tri, chinh tri, minh thu
manh tri » thanh tri, dinh tri, manh tu
cac nuoc » cap nuoc, hoc nuoc, dat nuoc
te sach » toc sach
cac xuc » cam xuc, chat xuc, cac cuoc
hieu ve » hieu va, hieu van
lang xa » lang ha, dang xay, lang van

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 tay lang xa hoi. hieu ve ((cac xuc) or (cac nuoc)) va ((manh tri) OR (minh tri)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach tay lang xa hoi. hieu ve ((cac xuc) OR (cac nuoc)) va ((manh tri) OR (minh tri)) cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach tay lang xa hoi. hieu ve ((cac xuc) or (cac nuoc)) va ((manh tri) OR (minh tri)) cua triet*".
