Qinghai Qarhan Salt Lake.

Qarhan Salt Lake Ten Thousand Zhang Salt Bridge: In fact, it is a wide avenue paved with salt built on the salt lake. It has neither piers nor railings, and the entire road surface is flat and smooth, as level as a grindstone. It looks almost the same as the asphalt roads in the city. The terrain around the salt lake is flat and the desert is boundless, but the scenery is unique. When the weather is fine, the vast lake surface is like a huge treasure mirror, emitting a silver glow, steaming with heat, and sparkling with waves, truly resembling an ocean of blue waves. The lake also produces pearl salt, known as the "largest salt lake," with each grain as pure white as snow and as clean as jade. Glass salt, also known as crystal salt, mostly appears in block form, transparent like glass. Freshly unearthed glass salt comes in colors such as yellow, orange, blue, pink, and milky white.
