Similarly, the community bulletin board is also a means for residents to acquire scientific and popular knowledge and acts as a "message bearer" to mobilize the entire population.

With the advent of the internet era, activities such as networking for socializing and information gathering, engaging in e-commerce, and publishing information and sharing resources through website construction are all closely related to promoting this event. Electronic virtual bulletin boards are typically sections on corporate, government, institutional, and community websites used to promote their own situations and specific matters, and are consistent in purpose and function with traditional bulletin boards.
