Xiao Zijian is like an encyclopedia, talking eloquently.

According to the records of the Book of Jin and the Geographical Chronicles, in the third year of Yongshou in the Eastern Han Dynasty, that is, in 157 AD, the population of the Central Plains at that time was 56.48 million, and in the first year of Taikang in the Western Jin Dynasty, that is, in 280 AD, the population of the Central Plains at this time was only 16.16 million. In just over 100 years, the population of China has plummeted by more than 30 million.

The population of the Han nationality in the Central Plains has plummeted, while the ethnic minorities in the north have migrated inward on a large scale, and the ethnic structure has also undergone tremendous changes.

In 299 A.D., Jiang Tong said in the "Treatise on Migration": "There are more than 8 million people in Guanzhong, and the rate is much less, and Rong Di is half." You can see the sheer number of them.

In such a historical background, different ethnic groups began to gradually merge, culturally, the Central Plains culture assimilated the ethnic minorities, but physically, integrated the strong physique of the northern ethnic minorities.

At the same time, the number of Han people in the south not only did not decrease, but during the Wuhu Rebellion, many Han people from the Central Plains poured into the south and increased.

Compared to southerners, northerners are taller, longer-legged, and have a stronger physique, which is more prominent in their martial arts. For example, boxing techniques are often used to smash, collapse, and hammer, and shots also emphasize picking, rushing, and colliding, etc., and the foundation of these skills lies in the advantage of strength. As for the use and skills of the leg method, the southern school is far inferior.

Therefore, for a long time in history, the northern martial arts were stronger than the southern martial arts.

Until the Song Dynasty, Zhao Kuangyin created the 'Taizu Long Fist', and later there was the 'Yue Family Sanshou', emphasizing the need to win quickly, shooting fiercely, emphasizing the stitches and needles when fighting, and making progress close to the body, and focusing on interlocking techniques. The greatest contribution of the Yue family is that when fighting, the emphasis is on seeing the seams and inserting the needle, and the progress is close, which directly forms the characteristics of the Southern School of martial arts, and also lays the foundation for the emergence of inch strength, which lays the foundation for the Southern School of martial arts that does not pursue to defeat the opponent in strength, but pays attention to the attack strength of the moment of hitting.

Later, Zhang Sanfeng founded the inner boxing, revolutionized the creation of internal strength, relying on wisdom to make up for the physical gap between the northerners, after nearly a hundred years, it was equal to the northern martial arts in the Ming and Qing dynasties.

However, the northern martial arts are not the same as the outer boxing, and the southern martial arts are not equal to the inner boxing.

The regional difference between the northern and southern martial arts only forms different martial arts techniques, and the inner and outer martial arts are about the method of exerting force. Since ancient times, regardless of the northern and southern school martial arts, the real large-scale use is foreign boxing, because it is easy to learn quickly. Even in modern times, the inner boxing emphasizes talent, enlightenment, and heart, which takes a lot of time, and it may not be able to do the same realm of foreign boxing masters. Therefore, whether it is a northern martial art or a southern martial art, most of the boxing techniques belong to the category of foreign boxing.

This is like the outer boxing is a practical product, which can be mass-produced, and the inner boxing is a work of art, if you want to have achievements, you can't find it.

Xiao Zijian gave Lu Shanmin a vivid lesson in the history of Chinese martial arts, this rich boy who seems to be a good man, no matter whether he has achievements in martial arts or not, at least he is a well-read person. This made Lu Shanmin feel a little good about him.

Although Liu Yiyi is from the north, as the name of her gym suggests, she is not limited to northern martial arts.

Next, two groups of students took the stage to perform Tai Chi Tui Shou and Wing Chun Seeking Bridges, both of which are typical southern martial arts, but they are also routine performances, which do not have much practical significance.

Liu Yiyi slowly walked to Sheng Tian's side, saluted him elegantly, and made it to his side.

"The fact that the Sheng seniors can come in person flatters the younger generations."

Sheng Tian just glanced at Liu Yiyi lightly.

"Liu Tianxu is in good health"?

"Thank you seniors for your concern, grandpa is in good health."

Sheng Tian smiled faintly, "As early as more than ten years ago, he broke through the middle stage of the Mountain Moving Realm, I'm afraid it's not as good as you said."

Liu Yiyi smiled, "Senior Sheng is a once-in-a-century master of internal boxing, internal boxing is healthy, and external boxing hurts the body, so naturally it is not as good as the predecessor's health."

As he spoke, he said, "More than ten years ago, grandpa beat you by a move, I'm afraid now I will lose by you."

Sheng Tian smiled, he was not angry because of Liu Yiyi's words, and he was angry with a junior, he was not so stingy.

"You really deserve to be Liu Tianxu's granddaughter, with sharp teeth in the same vein."

Liu Yiyi smiled, "Thank you for the compliment."

"Do you know what I said to your grandfather after I sparred with him?"

"Uh.... I would like to hear about it".

"I told him that if you practice martial arts, you will practice martial arts, and if you do business, you will be in business, and if you are not literate or martial, the Liu family will be removed from the martial arts family sooner or later."

Saying that, he glanced at Liu Yiyi lightly, "This sentence is also given to you today, otherwise you will never be able to climb to the peak of martial arts."

Liu Yiyi smiled, "Thank you seniors for your advice, however, my grandfather said that a person who practices martial arts is always a dog in the family of a rich and powerful person, and I think grandpa's words are even higher."

Sheng Tian frowned slightly, he didn't expect this young junior who looked exquisitely to say such a thing to him.

However, the mood of the inner boxing masters is better, and of course he knows that Liu Yiyi is deliberately provoking him.

smiled, "Don't worry, I'm just coming to see, I'm so old, if I still come to compete with you, a junior, I won't be laughed to death by Liu Tianxu."

Liu Yiyi smiled easily, when she saw Sheng Tian coming, although she knew that he would not smash the field regardless of his identity, but with this top master here, she was still nervous. Now that I got a positive answer from the other party, the stone in my heart finally fell.

When asked this sentence, Liu Yiyi did not have a gentle smile on her face, but unconsciously revealed a strong fighting spirit.

Sheng Tian smiled leisurely, "You are quick-witted, you must have spent a lot of energy on mundane things, Dongqing doesn't have so much thought about you, you dare to act straightforwardly, your chest is naturally open-minded, how do you compare."

Liu Yiyi smiled, "I really want to learn from her when I have the opportunity."

Sheng Tian didn't care, raised his hand and looked at his watch: "For Liu Tianxu's sake, I'll give you a word."

Liu Yiyi smiled indifferently, "Listen to me."

"The East China Sea is not Tianjing, do your duty."

Of course, Liu Yiyi knows what Sheng Tian means, the Liu family's grand plan security is to do security business, and at the same time, the Liu family is a martial arts family, which means that the Liu family will not care about expanding the security business or opening a boxing gym in the East China Sea, but if you want to do other things, I'm afraid it will not be so easy. The reason why Sheng Tian came in person today was probably to tell her this.

"Sheng seniors rest assured, juniors have their own measure."
