As early as May 2018, Twelve Behind had already introduced "Shuanghe Cave, after 31 years of exploration, finally becomes Asia's longest cave." A feature article dedicated to the cave was featured across dozens of pages in the main issue No. 691 of *China National Geography* magazine. At that time, the confirmed length of Shuanghe Cave stood at 238.479 km—but today, its explored length has grown to an impressive 437.1 km. And with ongoing international cave expeditions led by expert researchers each year, this figure continues to break new records. As a result, Shuanghe Cave has rightfully earned its title as Asia’s longest cave, firmly cementing its position as the region’s undisputed champion.
From the "Peak of Length" to the "Peak of Aesthetics," from "length" to "beauty," and from "quantity" to "quality"—Shuanghe Cave has achieved a stunning transformation over seven years. Hidden deep within the mountains of Suiyang, Guizhou, this underground palace has repeatedly captivated the world from entirely new perspectives, writing a legendary chapter in China’s cave exploration history.
