cau luc » cau truc, cau phuc
mang xa » lang xa, mang may, dang xay

va kinh » va tinh, qua kinh
cau tuc » cau truc, cau tu, cau phuc
su sac » su sach, su cac, su xac
sac ky » cac ky, sai ky

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sac ky ((mang xa) or (lang van)) hoi. lieu va ((cau tuc) OR (cau luc)) va kinh vai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky ((mang xa) OR (lang van)) hoi. lieu va ((cau tuc) OR (cau luc)) va kinh vai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky ((mang xa) or (lang van)) hoi. lieu va ((cau tuc) OR (cau luc)) va kinh vai cua triet".
• Adding a wildcard symbol may retrieve word variants: su sac ky ((mang xa) or (lang van)) hoi. lieu va ((cau tuc) OR (cau luc)) va kinh vai cua triet*.
