1928年3月，美国探险家约瑟夫·洛克在木里王的帮助下，踏上了一条穿越神山秘境的道路，深入当地称为念青贡嘎日松贡布的地方，就是如今的稻城亚丁地区。

In March 1928, American explorer Joseph Rock embarked on a journey through the mysterious mountains, delving deep into an area that is now known as the Daocheng Yading region.

洛克被这里壮美的景色折服，随后在美国《国家地理》杂志发表了相关文章和沿途所拍照片，在西方引起巨大轰动，也把这块“蓝色星球上的净土”第一次展现在世人面前。当初探险队伍从木里穿越到贡嘎岭地区的这条线路，后来被称为“洛克线”。

Rock was captivated by the breathtaking scenery here. Subsequently, he published articles and photographs of his journey in the National Geographic magazine, causing a sensation in the West and introducing this "pure land on the blue planet" to the world for the first time. The route the expedition team took from Muli through the Gongga Mountains to the region later became known as the "Rock Line."

“洛克线”令无数探险爱好者趋之若鹜，近一个世纪后，来自法国的留学生李查在当地探险家老尹的带领下，重走这条世界级的高原徒步路线，开启了一次穿越时空的探险之旅，去寻找香格里拉的真正意义。

The "Rock Line" attracted numerous adventure enthusiasts. Nearly a century later, a French exchange student Richard, under the guidance of a local explorer Old Yin, retraced this world-class high-altitude trekking route, embarking on an adventure through time and space to Shangri-La.
