Let me tell you the contents of the book, Bai Ling.
Generally, real masters don't write works casually, such as going out for an outing today, playing chess with old friends, meeting old friends I haven't seen for years, snowing, Mid-Autumn Festival last month and so on. They will integrate their emotions into their writing, and they will also write their own poems and articles. Although they love to do so, they will also sing and write other people's poems and songs to express their feelings. Usually they practice calligraphy with waste paper, and they don't keep it.
A master who plays the fool generally likes to write four words, because he often practices and watches them, and most people really can't see his true level when writing. The four common words are "generous and virtuous", "quiet and far-reaching", "Heaven rewards diligence" and so on.
