1. Wang Guowei said in "Words on Earth": "Great achievements have been made in ancient and modern times", and college inquirers must go through three realms: "Last night, the west wind withered the green trees. I climbed the tall building alone and looked at the end of the world". This first realm is also, "My clothes are getting wider and wider, but I don't regret it." This second realm is also, "I am looking for him in the crowd." Accompanied by a confidante, reading at night, holding a cup of tea, the beauty is eye-catching, the beauty is cultivated, and it is enjoyable and enviable. The second is "the grass is not removed in front of the green window." Because I am obsessed with reading, I forget the passage of time and the change of seasons, and the four seasons are reincarnation, and I don't know it outside the window. This is an admirable reading realm of concentration, concentration and forgetfulness. The third is "reading forbidden books behind closed doors on a snowy night". This kind of interest in reading is different from what I said before. It's freezing in the cold, snowing in succession, being silent all around, being alone, reading behind closed doors, and reading forbidden books. You can imagine the eagerness of reading, the relaxation and comfort of reading. You enjoy this situation and enjoy it, but it's not enough for outsiders.
