Busking (or street performance) refers to the form of entertainment where people perform in public area. Busking started in Europe on the 19th century, and spread throughout America, Australia and Asia (W, 2018). The entertainment can be present in various forms such as singing, playing musical instruments, performing magic and drawing. Since busking can take place anywhere (i.e. streets, footbridge and public areas in front of shopping malls), it raises issues regarding to the usage and noise of public area (Simpson, 2011). Many countries, for example Australia, Singapore, United Kingdom and Japan, have started policies to give guideline and issue license to buskers. In Hong Kong, conflicts between buskers and pedestrian become serious since the abolition of the pedestrian precinct in Mong Kok in August 2018. Voices of reinforcing laws for busking regulation has been raised, and thus the use of “Open Stage” has been started (香港特別行政區政府新聞公報, 2018).
