The reason why the ancients wrote traditional Chinese characters in calligraphy was probably because the use of complex and simple characters was a trend in the development of Chinese characters. In the evolution of Chinese characters, simplified characters were a trend that appeared under special circumstances. For example, in military propaganda, political propaganda, writing norms, etc., simplified characters were more convenient to use and spread. However, in most cases, people still use traditional Chinese characters. This is because traditional Chinese characters have their own unique charm in terms of strokes, structure, meaning, etc. These charms are not only the charm of the Chinese characters themselves, but also the charm of Chinese culture. Traditional Chinese characters were also an important part of calligraphy works. They not only showed the skills of calligraphers, but also represented the essence of Chinese traditional culture. The ancients wrote traditional Chinese characters not only for the use and transmission, but also to reflect the unique charm of Chinese characters and the essence of Chinese culture.
