cua tre » cua te, cuu tre, dua tren
va hanh » van hanh, va thanh, ban hanh

x hoi » xa hoi, o hoi, x ho

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: thuat khanh ly hang x hoi. hieu ve cau truc ((va hanh) OR (va danh)) di ((cua tre) OR (cua triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat khanh ly hang x hoi. hieu ve cau truc ((va hanh) OR (va danh)) di ((cua tre) or (cua triet))~".
• Adding a wildcard symbol may retrieve word variants: thuat khanh ly hang x hoi. hieu ve cau truc ((va hanh) OR (va danh)) di ((cua tre) or (cua triet))*.
