This painting on the Berlin Wall could counted to be the sociocultural literacy. The words in German means that “there are still a lot of walls need to be torn down.” It shows German people’s best wishes to be whole and united. I would like to use this picture to make a conclusion in the language world, that is, we need to tear down the wall in the langauge world. all languages should not be separated or categorized into different levels. We need to treat every language as national treature and treat them respectfully. On one hand, we accept the change; on the other hand, we have to take actions to keep them survive hamorniously.
