This is a glass entrance and exit of a modern public space. The inner side of the entire glass wall and door is printed with the word Welcome in hundreds of different languages around the world. The English word WELCOME is repeatedly decorated in striking red among dense white characters, and the Chinese characters for welcome can also be seen. The transparent glass has a mirror reflection effect, reflecting the red ceiling, long strip lighting inside, and the blurry shadow of the outdoor street scene. The design conveys an open and inclusive friendly atmosphere for all visitors, which fits the spatial attribute of enter and exit, and has both artistic sense and practical identification.
