Ionian grey, like the grey poetry condensed over the years, lies quietly in the river of time in a low-key and luxurious way. Its colour, just like the morning mist light cage of the old castle, calm through the deep mystery, introverted and magnificent atmosphere. The lines show the incomparable power and solemnity. They are spaced in an orderly manner, and each line contains the ultimate pursuit of order and harmony, which silently speaks of the spirit of perseverance.
