    Great Wall of China--A line of fortifications extending about 2,414 km (1,500 mi) across northern China. Built in the third century B.C. by some 300,000 laborers (mainly criminals, conscript soldiers, and slaves), the wall proved ineffective against invaders and is today a major tourist attraction.

    Abacus--One of the earliest counting instruments. Similar devices predate the Greek and Roman days. It uses sliding beads in columns that are divided in two by a center bar. The top is "heaven," where each of two beads is worth 5 when moved to the center bar. The bottom is "earth," where each of five beads is worth 1 when moved toward the center.

    萬里長城 Great Wall

    The Great Wall of China, one of the greatest wonders of the world, was enlisted in the World Heritage by UNESCO in 1987. Just like a gigantic dragon, the Great Wall winds up and down across deserts, grasslands, mountains and plateaus stretching approximately 6,700 kilometers (4,163 miles ) from east to west of China. With a history of more than 2000 years, some of the section of the great wall are now in ruins or even entirely disappeared. However, it is still one of the most appealing attractions all around the world owing to its architectural grandeur and historical significance.
