In the next few days, Li Liang sorted out the general content of the Ebbinghaus memory method that he had mastered in his previous life and compiled it into a booklet, he was going to let Chenchen and Junjie try this method first, especially the periodic memory method, which divided the content of memory into eight cycles, and strengthened memory according to these eight cycles, which would have twice the result with half the effort.

1. First memory cycle: 5 minutes

2. Second memory cycle: 30 minutes

3. Third memory cycle: 12 hours

4. Fourth memory cycle: 1 day

5. Fifth memory cycle: 2 days

6. Sixth memory cycle: 4 days

7. Seventh memory cycle: 7 days

8. Eighth memory cycle: 15 days

Chenchen's mother Chen Chunhua and brother Zhang Meng are busy running the restaurant every day, and her father and two older sisters are also at work, and she is responsible for eating and drinking herself and her younger brother Junjie every day. It just so happened that Li Liang was also at home alone every day, and the three of them happened to be together every day to verify the memory method summarized by Li Liang.

According to the requirements of the memory method, Chenchen and Junjie reviewed the textbook knowledge again for about half a month. Li Liang used the half month to compile a set of comprehensive test papers for the second year of junior high school students to test Chenchen's learning effect, and for Zhang Junjie, Li Liang also wrote a set of test papers for the fifth grade.

It took a whole day for Chenchen and Junjie to finish the whole set of papers. Li Liang was revising the test papers for their sister and brother, and Chenchen and Junjie were eating melon seeds while waiting anxiously for their test results to come out. Through this half-month of study, Chenchen and Junjie think that they have mastered the knowledge of this semester more finely through the systematic use of learning methods, but the specific results are also the test paper test of Li Liang.

After correcting the test paper, Li Liang put down the red ink pen in his hand, Li Liang put his mind at ease, through this test, Li Liang further verified his ideas, through the systematic use of mnemonics to learn, it can indeed help improve academic performance. After revising Chenchen and Junjie's test papers just now, Li Liang found that compared with the previous final exam at the end of June, Chenchen and Junjie's mastery of knowledge was different.

"Chenchen, Junjie, I have already reviewed the test papers, and you have mastered it very well!" Li Liang looked at Chenchen and Junjie looking at him expectantly, and said.

"Let's talk about Junjie's test paper first, Junjie, I compared your test paper for junior high school, to be honest, although the test is also good, but some knowledge points are obviously not proficient enough! This time my test paper is mainly aimed at the weak points in your last exam, and there are several targeted test papers, but this time you have mastered it differently, and the test is good!" Li Liang commented.

"Oh yes!" Zhang Junjie is also very happy, mastering this memory learning method is very helpful for his future learning.

"Chenchen, in the last final exam, you scored 750 points, the third in the grade, and you did very well. I have also read your test papers, and there are some problems in them, such as the knowledge points of the same angle in mathematics, the inner wrong angle and the complementary inner angle of the same side are not very in place, and I have lost a lot of points in this regard;

Chenchen listened to Li Liang's praise and was very happy.

"Then there is still a month to go in the next summer vacation, and I am going to tutor the two of you to learn the main subjects of the third and first year of junior high school!" Li Liang continued, "Chenchen, the textbooks from your first year of junior high school can be used by Junjie, but we still need to find someone to borrow two sets of textbooks for the third year of junior high school!"

"I have the textbooks for the third year of junior high school, and my cousin Runrun and Lily have them!" Zhang Junjie said.

Chen Run graduated from junior high school last year, Chen Li graduated from junior high school this year, and now both of them are working in the Zhang family's restaurant. Although some children in rural areas no longer continue to study, they still cherish books very much, and they rarely lose the books they have learned after graduation.

"Then the three of us will go to the store tomorrow and ask them, and by the way, see how the business in the store is during this time! I wonder if your mother and the four of them are busy?" Li Liang said.

Chen Chen and Junjie applauded repeatedly, in order to cooperate with Li Liang to verify his memory method, the two of them had been studying for more than half a month, and it was time to go out and let off steam.

Chen Chunhua is very busy during this time, every day after the restaurant closes, it is often dark, and it is basically 8 or 9 o'clock in the evening after Chen Chunhua arrives home. Early the next morning, Chen Chunhua had to buy some meat and other ingredients from the county seat that were not available in the countryside and rushed to the restaurant, and she was very busy every day. However, although she is tired, Chen Chunhua's interest is very high, the restaurant business is good, and she makes a lot of money, so she naturally does not feel tired.

The next day, Li Liang took Chenchen and Junjie to the restaurant by No. 11, it was more than 10 o'clock in the morning, Chen Run and Chen Li, two sisters, were washing vegetables by the well outside the store, and saw a few of them sweating profusely came over, and hurriedly beckoned them to enter the store to rest. In the back kitchen, Chen Chunhua was steaming rice in the stove, and Zhang Meng was not seen.

"Mom, where is my brother?" asked Chenchen when he came to the stove.

"There is not enough rice, your brother went to grandma's house to carry rice!" Chen Chunhua replied, and then said to Chenchen, "Chenchen, Liangzi, you go to the outside hall and sit first, and pour water yourself when you are thirsty!"

After the official opening, Chenchen and Junjie came for the first time, full of novelty. Li Liang went to the counter to make a few glasses of ice water, drank it in one gulp, and half of the hot heat was suddenly extinguished.

"Brother Liang, this water is so delicious! If only you could drink it every day at home!" Zhang Junjie said as he drank the water.

"Wait until next year to let your mother buy a refrigerator and put it at home, and you can drink it every day!" Li Liang said with a smile.

In recent years, some civilian household appliances have begun to gradually enter the homes of the Chinese people, but due to the limited consumption level in small and medium-sized cities, especially in rural areas, it is mainly high-income families in some large cities that can afford to buy and use. However, according to the current profitability of the restaurant, the Chen family should be able to afford it by next year.

Chenchen was a little unconvinced, but she liked Li Liang's confident way of speaking and didn't make a sound.

Zhang Junjie has been following Li Liang to use the memory method for half a month to learn, and he has been a little blind to Li Liang's words: "Brother Liang, it would be good if it was really like that, then I want my mother to buy a lot of popsicles and put them in the refrigerator, and eat as much as I want!"

"It's definitely not possible to eat as much as you want, and you can only eat one a day at that time!" Li Liang teased him.

"One, okay, you can eat one!" Zhang Junjie is not very demanding.
