In terms of height they are worlds apart.
The world's tallest man, Bao Xishun today shook hands with He Pingping who claims to be Earth's shortest.
But these two men actually hail from the same region of Inner Mongolia.
Mr Xishun shakes hands with Mr Ping Ping
Bao Xishun, a herdsman from Chifeng, Inner Mongolia, was recently married in a traditional ceremony to a 28-year-old saleswoman from his hometown. At 5ft 6" Xia Shujian only comes up to his elbow and is half his age.
He claims he was of normal height until he was 16 when he experienced a growth spurt and reached his present height seven years later.
Mr Xishun was confirmed as the tallest person by thelast year.
Mr Pingping was born nearby in Wulanchabu city, Inner Mongolia. His father claims he was only the size of an adult's palm at birth.
He is now seeking to be registered as the world's shortest man by the Guinness Book of Recrods. He could be in for a disappointment though. While Mr Pingping is 73cms tall, the current holder of the title Lin Yih-Chih was measured as 67.5cm.
