A special excavator that could dance, play basketball, write and stack water cups became the major attraction during a machinery show held in Changsha, capital of Central China’s Hunan province, last week.

“Operated by a skilled driver, the heavy machine gets so smart,” said a show visitor.

The three-day Changsha International Machinery Fair, which opened May 15, received 1,150 machinery manufacturers and companies from home and abroad.

In addition to business talks and economic cooperation, many machinery companies showcased their latest technologies and new and unique machinery products during the fair to demonstrate them to visitors and attract buyers.
