Wang Xizhi's Preface to the Lanting Pavilion: "Looking up at the vastness of the universe and overlooking the prosperity of categories" seems to be a mountain peak on the edge of the ridge, with different heights. "The four seas are rising, and the scenery here is splendid; Kyushu stirs and opens mountains and rivers. Looking up at the sky, time is deeper; Bend down and work hard, and the future is infinite. The road is blocked and long, and it is ok; The journey is long, only struggle.
