19101012 was born in a small businessman's family in Jintan county, Jiangsu province, with a height of1.65m. My father Hua Ruidong runs a small grocery store, and my mother is a virtuous housewife. Hua was born when his father was 40. At the age of 40, the couple regarded their son as the apple of their eye. In order to bless their son, they buckled two baskets for him when he was born. Therefore, Hua got its name. After graduating from Renmai Primary School at the age of 12, he entered Jintan County Junior High School and fell in love with mathematics. One day, the teacher worked out a math problem of "I don't know the number of things". The teacher said that this is a famous math problem in Sun Tzu's Art of War: "Today, there are things I don't know the number of. Three or three numbers leave two, five or five numbers leave three, and seven or seven numbers leave two. What is the geometry of things? " "23!" As soon as the teacher spoke, Hua blurted out his answer. At that time, Hua had not learned Sun Tzu's calculation. He thought in the following wonderful way: "three-three numbers leave two, seven-seven numbers leave two, and the remainder is two." This number may be 3×7+2=23, and 5 divided by exactly 3, so 23 is the number you want. " Hua denied that he was a genius. 1925 after graduating from junior high school, he was unable to enter senior high school because of his poor family, so he had to study accounting in the Chinese vocational school founded by Huang Yanpei in Shanghai, in order to find a job similar to accounting to support his family. In less than a year, due to the high cost of living, I was forced to drop out of school and go back to Jintan to help my father manage the grocery store. In the monotonous life of standing at the counter, he began to teach himself mathematics. When he returned to his hometown, he continued to study mathematics while working for his father in a grocery store with only a small facade. Recalling the time when he studied hard, his sister Hua Lianqing said, "Although it was winter, Luo Geng was still reading his math book at the checkout counter. Snuff running down, he wiped his nose with his left hand and threw it aside. He didn't get rid of it, so he stretched out his right hand and kept writing ... "

At that time, Luo Geng stood in front of the counter. When the customer came, he helped his father do business, do abacus and keep accounts. As soon as the customer left, he buried himself in reading and solving math problems. Sometimes I am in a daze, forget to receive the customer, and even take the calculation result as the payment payable by the customer, which surprises the customer. Because similar inexplicable things often happen, after a long time, his neighbors treat him as a joke, and everyone has nicknamed him "Luo Daku". Whenever something happens that neglects customers, my father is angry and anxious, saying that he is too tired to read the "heavenly book" and wants to burn the book forcibly. When there is an argument, Hua always clings to the book.

Later, recalling this life, he said bitterly: "It was a year when I should receive education, but the word' poor' deprived me of my dream: wiping my nose, a pair of straw sandals and a cigarette, a roll of rush grass and a needle in the northwest tuyere, struggling to survive." Stubborn self-study to 18 years old. /kloc-married Wu Xiaozhi in the autumn of 0/927. From 65438 to 0929, Hua was employed as a clerk in Jintan Middle School and began to publish papers in Shanghai Science and other magazines. 1929 In the winter, he suffered from severe typhoid fever. After nearly half a year's treatment, he recovered, but his left leg joint was seriously damaged, leaving him with a lifelong disability. He had to walk on crutches.
