The issue of mixed use of traditional Chinese characters and simplified characters has always been one of the focuses of debate in the book world. So far, the jury is still out.
Mixed use involves two aspects, one is the mixed use of traditional and simplified characters in the same character (i.e. half-simplified and half-traditional), and the second is the mixed use of traditional and simplified characters in different characters in a calligraphy work, such as: Write "The lone sail's shadow is far away in the blue sky, but you can only see the Yangtze River flowing in the sky", and so on. The former's mixed use is a creation, with neither historical origin nor standard. It cannot and should not be mixed. There is no different meaning in the book world. The controversy arises from the latter. Opponents believe that: First, traditional Chinese characters and simplified Chinese characters were produced in different historical periods and should be regarded as two systems. If they are used interchangeably, they will appear nondescript. Second, calligraphy works are for people to appreciate. Mixing traditional Chinese characters and simplified characters can easily cause confusion in the use of characters for the appreciators. If the masses (especially teenagers) follow suit, it will become popular in society, resulting in simplified characters and standardized characters. Difficulties and obstacles in implementation.
