In the Song Dynasty (宋朝) there was a joker called Sun Shan (孙山).
One year he went to take the imperial examination, and came bottom of the list of successfulcandidates.
Back in his hometown, one of his neighbor asked him whether the neighbor's son had also passed.
Sun Shan said, with a smile:"Sun Shan was the last on the list. Your son came after Sun Shan."
The people used this idiom to indicate failing in an examination or competition.

Later, someone persuade him that his fears were groundless.

A man of the state of Zheng wanted to buy a pair of shoes.
He measured his foot and put the measurement on a chair.
When he set out for the market,he forgot to bring it along.
It was after he had found the pair he wanted that this occurred to him.
"I forgot the measurement", said he.
He went home to get it. But when he returned, the market had closed and he did not get his shoes after all.
"Why didn't you try on the shoes with your feet?" He was asked.
"I'd rather trust the measurement than trust myself."
