 The liangzhu culture, an incredibly ancient, now lost, yet once highly advanced civilization, one which once dwelled on the banks of the Yangtze River Delta in eastern China. The cultural advancements of this civilization have been of archaeological interest for a number of decades, particularly due to its similarity with the growth of our own modern civilization, throwing mystery onto how this once flourishing, class-driven civilization suddenly vanished. Burials were often found to have been practiced to different standards. This depended on the financial assets of the individual's family. However, nearly the entire span of this monstrous ancient civilization's ruins lay stratified. Academia has been kept busy documenting their pottery techniques, and the mastery they possessed in the manipulation of jade. Yet why they simply vanished some 4,000 years ago, after flourishing unabated from 5,300 years ago, has remained a thorn in their sides, one they were seemingly unable to explain without the partial admittance of an ancient great flood, a reality which it seems they have finally surrendered to. The investigations of this ancient civilization, although not widely known outside of China, have revealed that the civilization shows all the hallmarks of the other advanced global civilizations we have been researching worldwide, most probably linked, we feel. Canal manipulation for irrigation, advanced agriculture, and many other forms of evidence, including advanced plumbing and sewage systems, all lead us to this conclusion. Quote, Yet regardless of this single innovative millennium, the Liangzhu culture mysteriously collapsed around 4,300 years ago, and the ancient city was abruptly abandoned. Exactly why has never been fully understood, although many have suggested some form of catastrophic flooding led to this sudden decline. A thin layer of clay was found on the preserved ruins, which points to a possible connection between the demise of the advanced civilization and floods of the Yangtze River or floods from the East China Sea. Geologist Christoph Spudel from the University of Innsbruck in Austria has finally admitted. We find such conclusions, and indeed the ruins in which they were enveloped highly compelling.
