Lu Chao


Lu Chao

Lu Chao (simplified Chinese: 吕超; traditional Chinese: 呂超; pinyin: Lǚ Chāo) from China is the recognized Guinness record holder for reciting digits of Pi. He successfully recited 67,890 digits of pi in 24 hours and 4 minutes[1] with an error at the 67,891st digit, saying it was a "5", when it was actually a "0". He stated he had 100,000 memorized, and was going to recite 91,300, but that one mistake cost him. He is planning to write a book about the method he uses, which is based upon many Chinese memorization techniques. He says it took him about 1 year to memorize 100,000 digits. He has no plans to beat his record unless someone else does.[2] Lu Chao is the President of Zhengzhou Ruicheng Education & Counseling, Ltd.
