In the Han Dynasty, Keju was already popular.

At that time, there were two kinds of balls that people kicked, one was simple to make, and directly used hair or wool to "tangle it", called hair balls, which were less durable, and the kick was not too far;

The other is the Tang Yan Shigu said "to Wei for it, real to things", Wei is a soft leather made of hair processing, sewn into a ball bag, which is stuffed with animal hair, this kind of solid ball easily reminds us of the waste paper ball wrapped in a plastic bag when we were children, but it is more high-end than the hair ball, and it is commonly used in the Xuchang Palace at the end of the Eastern Han Dynasty.

Sports historians believe that this kind of solid ball with leather shell appeared in Yin Shang at the latest, because the word Ju at that time was biased from the leather, and there was a bow dance during the sacrifice.

In the Tang Dynasty, the production of football had a qualitative improvement, from a solid ball to an inflatable ball. There are many references in the poems of the Tang Dynasty, for example, Gui Shizi said in "Answering the Day and Breaking the Skin Poems" that "eight sharp waves are made into balls, and the fire is boiled in the water and kneaded", and Zhong Wupo said in "Balloon Fu" that "dedication to the rules, the first cause is the square; The prosthetic hand fills the seams, and finally makes it full but not overflowing"; Xu Jian, who was very popular during the Tang Xuanzong period, also described in "Beginner's Notes", "Today, with the skin, the cell is the inside, and the breath is closed and the foot is closed."

Synthesizing these materials, it can be seen that the football in the Tang Dynasty is more called a ball, rather than a bow, and the leather treatment has to go through multiple processes such as water kneading and fire roasting, and when making the ball, the leather is first cut into squares, and then sewn into a shell with a combination of eight pieces of skin, of course, this shell will certainly not be as round as the football made of thirty-two pieces of leather today.

And the most important point is that the ball in the Tang Dynasty already had an "inner tank", which is the urine of animals. This should be the world's earliest inner ball, according to the history of world sports, Britain invented the invention of the ball, in the 11th century, three or four hundred years later than our country. The ball in the Tang Dynasty had to be blown with the mouth, and then tied up, sewn up the shell, and then it could be kicked.

Balloons are certainly much more elastic than solid balls, able to kick higher and more entertaining, and as a result, this major advancement in equipment led to a major change in the rules of football in the Tang Dynasty compared to in the Han Dynasty. There are several people in the folk game of playing, which is called "white fighting", "surround and kick, do not fall to the ground, be ashamed of losing your foot, and do not fall for a long time";

There is also a pure competition for who kicks high, called "Baoju", Wang Wei's "Cold Food in the East of the City" has "Keju repeatedly over the birds", which is talking about this kind of gameplay.

After entering the Tang Dynasty, the strength players who were resistant to carrying and falling on the competition field were no longer popular, and ancient Chinese football locked in the "technical flow".

The goal was changed from six on one side of the Han Dynasty to one shared by both sides, from a low goal to a high goal, and the one who kicked the ball through the net hole won the game, and the direct confrontation between the two sides became an indirect confrontation. Therefore, since the Tang Dynasty, the scene of long-distance running with the ball no longer appears, and players are more concerned about stopping the ball and shooting skills.

Of course, Li Zexuan naturally didn't understand these situations, and he didn't need to understand them, what he wanted to do was to bring modern football and football rules to the Tang Dynasty. When the time comes, wouldn't it be nice for this heavenly kingdom to hold the World Cup again every four years? Whoever dares not to come is not to give face to Datang, and not to give face to Datang....

"Yah~! Xianggong, this ball is lighter than the hollow ball sold in Chang'an City, and it is more elastic, how did Fu Bo do it? ”

Han Yuxi took the ball from Li Zexuan's hand, tried it, and was immediately surprised.

Li Zexuan smiled as a matter of course: "Hehe, this is made by the workshop with the latest technology and the latest materials, and only our family can do it in the entire Datang, and others can't do it even if they know the method, haha~!" ”

Han Yuxi returned the ball to Li Zexuan and asked, "Does Xianggong plan to use this ball for the students?" ”

As Li Zexuan's pillow person, Han Yuxi knew that her father-in-law was not very interested in making money now, so she guessed that this kind of light and elastic ball should be specially made by Li Zexuan to play.

"Well, that's right! If you don't get some entertainment for those little bunnies, they will always be idle and do things~! ”

Li Zexuan put away the football, walked into the house with Han Yuxi, and replied by the way.

In fact, football is not all for the students, but also for himself, and he also wants to play football.

In his previous life, he was a pseudo-fan, because his body was relatively weak, he couldn't bear to run for a while, so he was just an off-field fan, and he usually only watched football games, and rarely played in person.

Of course, he only watches the football games of other countries, not that he is not patriotic, but the football of his own country...............

In this life, he is strong, wealthy and in a high position, he wants to develop football in Datang, so as to build a football powerhouse to make up for the regrets of his previous life.

If you want to promote football, of course, you have to start promoting it from the academy, after all, it is here that more than half of the "second generation of officials" in Chang'an City are gathered.

"But Xianggong, isn't the academy a place for students to study?"

Han Yuxi asked.

"Hey, I don't know if the lady has ever heard of the combination of work and rest? And my husband thinks that only students who can play will have good academic performance, and they can't even play, so what is learning about? Ha, go and add some patterns to this ball for your husband, lady, you go and get busy! ”

....................

The next day, Saturday.

The students, who were supposed to be on vacation, were still undergoing military training at school.

It is worth mentioning that some parents saw that their children did not come home yesterday, for fear of accidents, and went to Yanhuang Academy last night to inquire about the situation! After learning that it was the college that was on vacation, they left with peace of mind.

Under their word of mouth, more and more people knew about the Yanhuang Academy's leave, and the parents who had not yet gone to the Yanhuang Academy to inquire about the news also saved an extra trip.

"Alas, boring! If I had stayed on the line, I would have been sleeping in bed by now! All evil military training, all evil rest~! ”

During recess, Sun Zifan lay on his back on the grass and sighed with a wistful expression.

"It's boring, but it's only a few days left, and you can officially start classes later, so it should be much more interesting by then~!"

Li Tai rubbed his belly, which was getting more and more shriveled, and said sullenly.

In the past, his "proud" belly wood was there, and he was blue!

"Damn, I'm going to pee, it's time for military training in a while~!"

Sun Zifan rolled around with a carp and suddenly stood up from the grass.

Coincidentally, at this moment, a black and white spherical object roared over, and in the blink of an eye, it hit Sun Zifan's face.

"Bang~!"

As soon as the little tease got up, he fell down gorgeously.
