When Hua sold cotton to a lady, she found that the toilet paper she had just used up was taken away by the lady. This made Hua very anxious, and he went after the lady desperately. He finally caught up with her. Hua said shyly, "Auntie, please … please give me back the toilet paper." The woman said angrily, "I paid for it, but it wasn't from you."
Hua was in a hurry and said, "How about this! I paid for it. " When Hua reached for the money, the woman seemed to be moved by the child! He not only asked for money, but also returned the toilet paper to Hua. At this time, HuaCai slightly relieved. After returning home, I began to calculate math problems again. ...
2. Hua is not only willing to think for mathematics, but also pays great attention to Chinese. On one occasion, the teacher distributed his collection of books by Hu Shi, a literary master, to the students and asked them to write a review after reading them.
Hua's copy is a collection of attempts, which reveals the author's pride in advocating vernacular Chinese and thinks that he is a successful experimenter, so he wrote a preface poem on the title page: "Since ancient times, attempts have never been successful, and it may not be true. I am the next topic today, and I have been trying successfully since ancient times. "
3. When Hua is studying, he seriously thinks about the traditional abacus method. He believes that the addition and subtraction of abacus is difficult to simplify, but multiplication can be simplified. The traditional multiplication method is "leaving the head" or "leaving the tail", that is, multiply first and then multiply by the multiplicand; Whenever a number of the multiplier is multiplied by the multiplicand, the number is deleted from the multiplier; Use up the multiplier to get the final answer.
Hua thought: Why not simply add up the abacus answers one by one? This saves the time to calculate the multiplier on the abacus, such as 28×6. Put 2×6= 12 on the abacus first, then retreat one place and add 8×6=48 to get 168 immediately. It only takes two steps to get the result. For division, it can also be converted into gradual subtraction to save more time.
With this and his mental arithmetic, Hua won the championship in the abacus competition held in Shanghai at that time.
4. Hua especially likes thinking. He often shows great interest in other people's seemingly ordinary things and asks some seemingly strange questions.
Once, he went to the suburbs to play with others and saw a stone man and a horse beside an abandoned grave. He asked his older companion, "How heavy are these stone men and horses?" The companion replied, "How do you know?" Unwilling, Hua thought for a moment and said, "There will always be a way to know."
In Jintan, Hua's favorite places were Lantern Festival, Dragon Boat Festival and Temple Fair. In all these busy places, he is indispensable. There is a Qinglong Mountain in the east of the city and a temple on the mountain. Every temple fair, the bodhisattva in the temple will put feathers on his head, put on colorful clothes and ride a big horse into the city. Along the way, people kowtowed to the Bodhisattva and prayed for happiness.
Hua straightened his neck and looked at the Bodhisattva with folded hands, thinking, "Is the Bodhisattva really omnipotent?" When the temple fair broke up, people went home one after another, but Hua followed the "Bodhisattva" to Qinglong Mountain, trying to find out the truth and see the true face of the "Bodhisattva".
