Confucianists can say that writing is used to convey Tao.Husband and Taoism are so deep and unpredictable that secrets are not passed on, such as the heart seal of Buddhism and the formulas of Taoism!The truth of everything is the way.Therefore, the Dao is in the heaven and the earth, like mercury pouring down the earth, every particle is round, like the moon reflecting water, it can be seen everywhere.As big as governing the country and the world, as small as every thing, every movement and every word, it doesn't matter.Wen, one end of the way.The great text is the Six Classics, which is the foundation of the Tao; it is reduced to the history of the dynasties, it is reduced to the book of the philosophers, and it is reduced to the collection of Baishi. It seems that there is nothing to do with Taoism when you come down to barnyard official novels.However, Hanshu Yiwenzhi is listed as a family, and the bibliographies of all dynasties are also described. Isn't it absurd and paradoxical?Although they are not enough, they are close to the righteous ones, and they are not without benefit to people's hearts and morals!Mr. Hejian is highly regarded by the world for his academic articles, but he is lonely by nature. He doesn't like to flaunt his family with empty talk, and he doesn't like talented people to release their birthdays to poetry clubs and wine clubs, and to praise celebrities.Therefore, when I quit eating, I only linger on the classics, and I am old and lazy to research. I pick up strange news, take notes from time to time, and express what I want to say.The Luanyang Xiaoxialu and other five books contain everything strange and strange, and Guangyang speaks everything, but the main purpose must be pure and upright, in order to make people know what to persuade and punish, so the book of obscenity and desire is written as a gift for beautiful talents and talents Although the paper is expensive for a while, it will gradually disappear into oblivion, and the book of Mr. Li will be engraved repeatedly, and it will last for a long time.It is a clear test of the difference between China and reality.There are so many reprints, there are many errors, and there are those who make mistakes like the engravings of Ming people, and the readers are sick.When Shi Yansu traveled with Mr. Wang, he tasted the engraving and listened to it in vain. The postscript is attached to the end of the book. Mr. Wang thinks that he knows the words. Recently, the boards are full of confusion, so I asked Mr. Yu to combine the five books into one compilation, and still keep their original titles. The lamp hand school didn't dare to work hard, and asked the master to inspect it, and then copied it.Although it is not necessary to pass on the works of Mr. Yu at this moment, Yu Lu's mistakes are rarer than Mr.'s original annals of teaching the world, and there may be some small complements.
