余有一积习：但凡品诗衡文，务必披坚执锐，穷形尽相，力求读懂弄通，看真吃透。其间或遇佳者，每必振笔颜之，密圈加之，标识已克之城，示人未发之珍。(I have an old habit: As long as appreciating poems and having comment on the articles, I am sure to be fully armed and ready for combat, give a penetrating description, strive to read and understand thoroughly. During or in case of meeting best one, must be marked and punctuated to identify and show the precious part undiscovered by people.)
