公告

公告 (gōng gào) refers to an official notice or announcement, typically issued by an organization, government, or institution to inform the public about important information.

The character 公 (gōng) means 'public' or 'common,' and 告 (gào) means 'to inform' or 'to announce.' Together, they convey the idea of a formal message shared with the public.

公告 is commonly used in official contexts, such as school bulletins, company notices, or government decrees. It is more formal than everyday announcements and often appears in written form. In daily life, it may also be seen on bulletin boards, websites, or in printed materials.
