As for running script, running script is a rapid writing of regular script, which is said to have started at the end of Han Dynasty. It is not so neat as regular script, nor so scrawled as cursive script. The most famous masterpiece is Preface to Lanting written by Wang Xizhi, a calligrapher in the Eastern Jin Dynasty. Predecessors described it as "a dragon descending from heaven, a tiger lying in a phoenix pavilion" and praised it as "the best running script in the world". Tang Yan Zhenqing's book "Sacrificing a Nephew" is very bold, and the ancients rated it as "the second running script in the world".
Line means walking. As the name implies, the fonts written by lines are very vivid, practical and artistic.
