We are looking forward to visiting China's tallest country through Karakoram Highway (also known as China Pakistan friendship highway) to hongqilap. Unfortunately, we can only stop at the outpost three kilometers in front of the country. Although we have regrets, we are shocked by the company of Karakoram along the way, which is also a worthwhile trip! Karakoram mountain is one of the most awe inspiring mountain landscapes on the earth. It stretches for thousands of kilometers, northwest southeast, with an average altitude of more than 6000 meters. As a result, it has become the focus of geologists, mountaineers and tourists all over the world.
