年轻人喜欢实时留言和评论，我将这样的文化现象和传统街头文化结合，将人流量较大的公交车站等公共场所的显示屏作为留言墙，当人们路过这样的显示屏时，可以收到含有特制表情包（《天津大公报》中提取得来）的提示信息，如果愿意参与进来，就可以通过手机小程序在电子屏幕上使用表情包实时留言，表情包会和留言分离，产生有趣的互动。

Young people like to leave messages and comments in real time. I combine this cultural phenomenon with traditional street culture. I use the display screen in public places such as bus stops as a message wall. When people pass by such a display screen, they can receive prompt messages containing special emoticons (extracted from Tianjin Ta Kung Pao). If they are willing to participate in it ,You can use the emoticons to leave real-time messages on the electronic screen through the mobile phone app. The expression pack will be separated from the messages and generate interesting interaction.
