Recently, there are so many comedy variety shows to help people relieve pressure, which enjoy a great popularity. There are three main reasons why people like these programs: the rational release of negative emotions, re-experiencing and reflecting on life, and coping with challenges with optimism and confidence. At the same time, comedy needs to have unexpected endings, be infected by people around and satisfy people's pursuit of freedom, because people expect to find a show that fits their need, and move forward in laughter.
