Java is a miracle created by the collision of natural power and human civilization on the edge of the equator. It interprets the pulse of the earth with erupting volcanoes, engraves the glory of faith with long-standing cultural relics, and conveys ancient wisdom with elegant art. There is both hustle and bustle and quiet ancient charm here; the charm of Java lies in the long tradition hidden in the modern city, and the endless fusion of multiple beliefs. Setting foot on this land will start a shocking journey through geological time and space, the long river of civilization and the density of life, and feel the hot, deep and vital pulse on the backbone of the South China Sea. From the sunrise on the seaside to the night view of Jakarta, from volcanoes to industrial areas, Java has always been moving forward in the tension between tradition and modernity, nature and humanity. It is a thick book, every page is full of contradictions and harmony, waiting for the world to read carefully.
