By CCTV reporter Wu Guoxiu

China’s Zhusuan or the knowledge and practice of arithmetic calculation using an abacus¹, has been nominated by UNSECO for competition to be listed as World Intangible Cultural Heritage. The final result will be announced early next month. The time honored invention has been slowly fading away from peoples’ lives, but some are calling to preserve it.

"Before the age of calculators, this is what Chinese people used to do their sums. They’d move the beads³ on the abacus following certain rules. Each bead² in the upper deck equals five, those in the lower deck equals one. For example, if I do 5 plus 1, this is 6. And if I plus 12, this is 18," CCTV reporter Wu Guoxiu said.

Abacus nominated for World Intangible Cultural Heritage

Zhusuan, or the knowledge and practice of arithmetic calculation using an abacus, has a history of over 1800 years. The Chinese invention is considered as the world’s most ancient computer.

"The abacus can perform addition, subtraction⁴, division and multiplication⁵, and can obtain square roots, cubic roots and Gauss equation," said Su Jinxiu, deputy director of Chinese Abacus & Mental Calculation Dev’t. Assoc.

For centuries, the abacus was a major calculating device. It even helped to make calculations when China developed its first nuclear bomb in the 1960s.

But now, only some banks and shops used them as supplements to computers.

"But very few people learn how to use the abacus now," Su Jinxiu said.

Until the 1990s, abacus lessons were compulsory⁶ in primary schools; later they became a selective subject. And then it was totally removed from the curriculum.

But, abacus operation has developed into mental calculation. Some children learn this as an interest. Learners figure out results with an abacus in mind. And there are national contests.

Advocates of the practice say mental calculation can help improve children’s intelligence.

Today, the abacus is still an auspicious⁷ symbol of wisdom and wealth. In 2008, it was listed as a national intangible cultural heritage. People in the abacus association hope the valuable heritage won’t die.
