In late October 1998 to early December, by scientists, journalists and members of climbers composed of scientific exploration Expedition, which lasted more than 40 days, through nearly 600 kilometers deep in the dense forests, steep cliffs, fast-flowing Yarlung Zangbo Grand Canyon region has been unusually difficult to carry out scientific exploration study tours, access to the most scientific information, and enjoy exploring The world's wonders of the Grand Canyon, the realization of the human foot for the first time to wear Yarlung Zangbo Grand Canyon's magnificent feat in history.
