Besides Preface to Lanting, there are many other excellent works in China's calligraphy, such as Yan's rubbings, Yan's rubbings and Zhang Xu's cursive script, which all represent different calligraphy styles and schools and show the diversity and richness of calligraphy art. In addition, calligraphy has formed its own unique style and form in different historical periods and different cultural backgrounds, such as regular script, running script, cursive script and official script.
Therefore, although Preface to Lanting is an excellent calligraphy work, it cannot represent the whole of calligraphy. We should also know and appreciate other works and styles of calligraphy, so as to know and understand this art form more comprehensively.
