3:00pm-9:00pm	Social Event and Conference Dinner Banquet Join us for dinner at the Great Wall of China!  We will leave the hotel and have the social event and dinner at Juyongguan (Juyong Pass), one of the most renowned passes of the Great Wall of China. Stretching over many thousands of miles, the Great Wall of China was originally created after the unification of China in the third century BC. It was further extended, rebuilt, and enhanced during succeeding Dynasties, with much of what remains of the Wall built during the Ming Dynasty (1368 to 1644). The Wall is one of the great wonders of the world and was enlisted as a World Heritage site by UNESCO in 1987. Throughout history, Juyong Pass has been an important military stronghold, situated in a valley surrounded by mountains. The pass is also a beautiful scenic spot, with beautiful flowers and lush trees covering the mountains around the pass. We will travel to the Great Wall at Juyongguan by bus, where there will be time for climbing the Wall and socializing with friends, in addition to dinner. At night, it's a bit cold at the pass, so we recommend you bring a coat with you, in addition to comfortable shoes for walking and climbing.
