Metamorphosis is a Chinese vocabulary, and the pinyin is tuěbiàn, which originally means cicada slough and shell change. See the painting praise in Preface to Xiahou Zhan and Selected Works of Dong Fangshuo. Metaphor means that things change in shape or quality.

This word refers to the nature that a person or an organization changes its behavior and image due to the change of guiding ideology and becomes completely different from the original. It also means that a large number of nuclei are transformed one by one due to radioactivity and eventually become another element. This word used to be a neutral word, but now it is mostly used in the aspect of "commending", which means to transform the beautiful. Transformation is beautiful, because there will be changes. There is excitement brought by the expectation of new things, a break with the original, cherishing the process of transformation and embracing hope.
