A small resident of the city of Changchun, Jilin Province, at the age of 2.5 years, could already name by heart 300 digits of pi after the decimal point
According to the Chinese newspaper New Culture, Dong Luyang, now 3.5 years old, first demonstrated her ability at her uncle's wedding a year ago. In 3.22 minutes, in one breath, she accurately named 300 digits of pi after the decimal point.
Shao Liquan, the mother of a girl with a phenomenal memory, said that her daughter was not indifferent to numbers from the very beginning. When numbers were present in children's songs, she loved to sing them very much.
Little Dong Luyang can also recite Confucius's book "Di Ji Gui" ("Rules of Good Conduct for Children and Students"), which consists of 1080 characters.
Many people use pi to train their memory.
For example, in 2005, Lu Chao, a student at Northwest Sci-Tech University of Agriculture and Forestry located in Shaanxi Province, recalled 67890 digits of pi after the decimal point in 24 hours and 4 minutes without errors.
A 60-year-old Japanese man from the city of Kisarazu named Yuan Kouzheng in 2006 recalled 83,431 digits of pi after the decimal point for 16 hours, the article says.
