Why are some photos of the poet Gu Cheng wearing a very special white hat?

First, the poet once explained that this is an exit symbolizing the soul, just like a chimney. Of course, this explanation means humor and ridicule, and it is more of a subconscious habit.

Second, the hat is a costume in life. The decorative prop wearing the hat is Gu Cheng or the poet Gu Cheng.

Third, if you really say what this means, as someone once said, Gu Cheng's jeans-like hat is like a poet's closed and wandering inner circle. He confined himself to the circle of confusion and repeated demands, splitting and escaping in the ideal.
