Grandfather Wu's twins are in fifth grade now. According to their age, they should be in second or third grade, but what kind of family do they come from? They have to skip a grade, or else it would be a shame to buy Wang Chaoxia and Dian Zhongdian from Taobao. They've already mastered Star Mental Arithmetic, the second semester of sixth grade. So that's it. Sun Mofei is getting too cocky now.

The textbooks of this era were very different from modern textbooks. After the movement was rectified, the first set of textbooks for primary and secondary schools (full-time ten-year system) was urgently compiled. Half a year later, adjustments were made to change the "second simplified characters" to "first simplified characters".

Later, the second edition of the primary and secondary school textbooks (full-time twelve-year system) was adapted by the People's Education Press, and the second edition of this set of books took another five years.

Five years later, my country's Ministry of Education revised and adapted the textbooks. This set of textbooks was used until the end of 1992, which was another five years.

In 1993, the State Education Commission promulgated the Nine-Year Compulsory Education Syllabus for primary and secondary schools. Their set of textbooks was officially used when the school started in the fall of 1993 and was used until after 2000.

The first edition of the textbook underwent three major changes in just three years: the first edition was released in January, using the second set of simplified characters, for example, the character "雪" (snow) did not have the "雨" radical; soon in November it was replaced by the second edition, which replaced the second set of simplified characters; in the third year, the third edition was released, and several texts were replaced.

Politics at this time is too sensitive, and a lot of changes can happen within a year.

Professor Dong is particularly impressed by the textbooks he studied as a child. I think every child should be impressed by their first textbook. Knowledge is endless, and learning is a very important thing no matter what era we live in.

On this day, the parents of the brothers Peggy and George who attended the Red Star Primary School were called in because they had a fight with their classmates.

When Grandpa Wu heard the news, he was stunned for a moment. His two children were smart, very sensible, and had excellent academic performance. Since they were young, they had skipped grades under the influence (torture) of college students at home. They were simply two little geniuses in the family.

He was a little caught off guard by the fact that his parents were called to the police station because of the fight.

I happened to go home to get something this morning through the space, otherwise the Anguo Pharmaceutical Factory would not have known about this. Fifth Grandpa Shen decided to go to the school in person to communicate with the teacher to find out what was going on.

He put on the suit that he rarely wore, tied a tie, wore brand new big leather shoes, put on a hat, and drove to school.

Arriving at school, Grandpa Wu found the class teacher's office. When the class teacher saw Grandpa Wu, he was stunned for a moment, and then came to greet him warmly.

During the conversation, he called Guan Paige and Guan George's grandfather "Fifth Grandpa", and Fifth Grandpa's face instantly turned ugly.

"Teacher, I'm Peppa and George's father, not their grandfather."

The head teacher was also very embarrassed at the moment. She didn't expect that Peggy and George's father was so old. After the New Year, she put away her thoughts and quickly told Grandpa Wu what had happened in detail: It turned out that during the break, the two brothers had a dispute with their classmates over a basketball, which eventually turned into a fight.

After hearing this, Grandpa Wu frowned. He looked at the two brothers standing aside with their heads lowered, squatted down and asked the two children, "Sons, what's going on?"

George has been a scheming boy since he was a child. At this moment, he said before his brother: "Dad, it's Dong Xiaohui. He said his dad is the principal, so we have to give him the ball to play with."

Wow, it seems that this is not just a simple incident of grabbing the ball, it has now risen to the class level.
