To query street communities, you can use map applications, such as Google Maps and Baidu Maps, enter your address in the search box, and the map application will display street community information. You can call the local telephone number, such as the contact number of the street office, and ask the staff for information about the street community you belong to. You can also go to the local community bulletin board to see if there is any relevant announcement information, and usually announce the division and jurisdiction of street communities.
