On the long road of calligraphy in China, it can be said that all outstanding calligraphers and their immortal works have created the highest realm of artistic beauty, which is also an excellent embodiment of dialectics. Here, we can take Wang Xizhi, Liang Wudi and Emperor Taizong as examples. They spoke highly of Wang Xizhi's exquisite attainments and wonderful tastes in calligraphy. Liang Wudi praised it as "Tianmen, Yue Long, where the tiger lies in the phoenix que", while Emperor Taizong praised it as "flowing, leaping with dragons and tigers".
