hanh dao » lanh dao, thanh dat, thanh dam
va cham » va tham
va chat » van chat, va phat, cao chat
nang xa » nang x, lang xa, nang ma
sac ky » cac ky, sai ky
soc va » hoc va, loc va, doc va

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky nang xa hoi. hieu ((va cham) OR (va chat)) soc va ((hanh dai) or (hanh dao)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang xa hoi. hieu ((va cham) OR (va chat)) soc va ((hanh dai) OR (hanh dao)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang xa hoi. hieu ((va cham) OR (va chat)) soc va ((hanh dai) or (hanh dao)) cua triet".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang xa hoi. hieu ((va cham) OR (va chat)) soc va ((hanh dai) or (hanh dao)) cua triet*.
