The beauty of Liao Jing's books lies in harmony. On the one hand, he perfectly applied the principles of formal beauty such as symmetry, balance, neatness, strewn at random, interpenetration, avoidance and proportion, and perfectly unified the aesthetic orientation of opposites such as length, density, inclination, straightness and rigidity. The former is the natural expression of "playing thousands of songs and knowing the instrument"; The latter is to treat each other with courtesy and call each other a beautiful gentleman demeanor through conscious contradiction resolution and mutual negation of opposites. On the other hand, although Liao Jing's calligraphy styles are varied, and his face sizes are different, both beautiful in the north and free and easy in brushwork, Liao Jing can bring these distinctive works into his own style category, with beautiful and elegant, solemn and quiet brushwork as the main style, obeying the lyric theme of "still water flows deep".
