For daily training, just like Lin Feng's experience in his previous life, as long as the training is more than three days in a row, this week can be persevered to the end; If you stick to it for three weeks, you can stick to it for a month; Persisting for three months has become a habit, and it is uncomfortable not to train. During the ten days when Lin Feng studied seriously and taught several brothers, after the fourteen of them got up early for training and overcame the initial stage of physical fatigue and psychological rejection, everything became smooth, even Xiao Duanrui could insist on doing a hundred push-ups at a time, but the guards had already done two hundred, and even Chen Fei had already achieved one hundred and fifty.

Of course, Lin Feng was not completely idle, and mainly did two major things. One is to teach Li Yu and Li Congqian a second lesson, and the other is to successfully start his supermarket plan.

During this period, what made Li Yu the strangest was that since Li Jing heard Lin Feng's theory of change that night, he didn't see the punishment for Lin Feng, nor the reward for him, and he didn't even mention it again, but in an occasional casual conversation, he asked about Lin Feng's class for them, and listened to him lightly, and he didn't say anything, only said when Li Yu said goodbye at the end: "Continue to study seriously." ”

Li Yu was an obedient child, and the next day he dragged Li Congqian to Lin Feng's guest room. Except for Lin Feng not staying here at night, every morning after training, he would read in the guest room, or write and sketch.

Listening to the intentions of the Li Yu brothers, Lin Feng smiled, he was dizzy when he was reading a book, so let's go.

Lin Feng asked Li Congqian about his studies lightly while leading the two brothers towards the garden in the back. Halfway through, Lin Feng grabbed a branch that was protruding from the road and was a little obstructive, and after breaking it slightly, he brushed the leaves on it in the direction of the branch, turning it into a bare branch. Li Congqian did the same, and also broke a branch and played with it in his hand.

After a while, the three of them walked to the pavilion where they usually wrote poems, Lin Feng raised the branch in his hand and asked the two brothers, "Are the branches straight or curved?" ”

"Straight, of course." The two brothers said in unison.

"Really? What now? Lin Feng stretched the branch in his hand into the water, and the branch immediately became as if it were bent.

"Hey, how did it get crooked?" Curious, Li Congqian stretched out the branch in his hand into the water and found that the same thing had happened.

Lin Feng pulled out the branches, and the branches were still straight and straight.

What does this mean? Who's straight and whom? Who's right and who's wrong? It's not what we simply imagined, not to mention what you hear from others, and even what you see isn't necessarily true. Lin Feng still habitually drew what he wanted to say from the actual phenomena in life.

Seeing that the two brothers began to habitually meditate again, Lin Feng used a branch to draw two identical lines on the ground and asked, "Are these two lines the same length?" ”

"Of course it's the same!" It was Li Congqian who blurted out again.

Lin Feng used a branch to draw two sets of opposite brackets on both sides of the two lines, the upper group of brackets were outward, and the lower group was inward, and asked, "What now?" ”

"Hey, it looks like it's long on it." This time, Li Yu also felt strange. Of course, this is a very interesting visual test question in later generations, which can give people an illusion of vision through external aids.

"If you were to see the bracketed line segment first, would you think the line was long? Therefore, in this case, who is long and who is short, whether it is true or false, if you do not go to the field to measure, only by visual inspection, only by what you see with your eyes, the results obtained may not be correct. Lin Feng continued to guide the Li Yu brothers' train of thought.

Lin Feng took the branch in Li Congqian's hand, compared it to the same length, and then handed one to Li Congqian again, and instructed him to erect the branch, holding the two sections of the branch with both hands, and he walked to a distant place, erected the branch in the same posture, and kept himself and the two brothers in a straight line, and shouted: "His Royal Highness King Zheng, do you see which of the two trees is longer and which is shorter?" ”

Li Yu felt ridiculous, it was obviously the same length, why did it seem so different?

Lin Feng returned to the two of them, put the two branches together again, and said, "The distance determines the size of the effect we see. Teacher Lin once said in a casual chat that at the beginning of the establishment of the former Tang Dynasty, Li Shimin was good at fighting, but he was away all the year round, and the relationship between Li Yuan and the harem was naturally more estranged, while Li Jianmin was always inside, and the relationship with his father, mother, and concubines was very close. In other words, if one person is serving in front of you every day, and the other person is running around for your career, who should be close to whom and who should be far away? ”

After speaking, Lin Feng took a step forward, led the two brothers to a small bridge, pointed to the opposite bank in the distance and said, "Suppose we want to reach the opposite bank, and now, this bridge is blocked by two big trees. Lin Feng threw the two branches in his hand onto the small bridge deck, "The trees are very huge, we can't move them for a while, how can we get to the other side as soon as possible?" ”

"The only way to go around is to go around the edge of the pond." Li Congqian ran to the top of the small bridge, observed it, and turned his head to reply.

"Yes. Instead of the time-consuming effort of moving away the trees, we can go around the side, and although the distance is a little longer, the time to arrive at the last is not slow. Therefore, who is fast and who is slow, the most difficult depends on the result. As the saying goes, sharpening the knife does not mistake the woodcutter, and the sharpening of the knife seems to delay the speed of chopping wood, but in the case of sharpening the weapon, it will grab the front. ”

Lin Feng changed his words and led the topic to the topic of his explanation today: "Today, we talked about curves and straights, long and short, far and near, fast and slow, that is, from different angles, how to treat one thing, one person, one policy, look at things, whether the policy is good or bad, and distinguish between loyalty and treachery. ”

The key is to look at people. Lin Feng sighed secretly in his heart. In the sixth year of Kaibao (973 AD) when Li Yu was in power in the original history, the Song Dynasty sent people to the Southern Tang Dynasty to ask for the "Jiangnan Tujing", which was an obvious precursor to sending troops, but Li Yu still ordered someone to copy a copy and send it. In the same year, Lin Renzhao stayed behind in the southern capital, secretly told Li Yu, and persuaded him to take advantage of the time when the Song Dynasty was tired of conquest to go out to Shouchun to restore his homeland. Lin Renzhao even said: "On the day of the army, please raise troops to rebel outside the country, and the matter will be for the benefit of the country, and it will not become a family of ministers, and His Majesty will not premeditate." "I'd rather bear the notoriety myself, be defeated and annihilated, but also excuse the future master, what a loyal minister and good general, but Li Yu was afraid, so he quickly transferred Lin away from the front line. Subsequently, Li Yu sent Li Congshan to the Song Dynasty to pay tribute, Zhao Kuangyin set up a counter-plan, pretending to inadvertently lead Li Congshan to a studio, Zhao Kuangyin seemed to casually point to one of them and said, your General Lin Renzhao has surrendered, first send this statue as a token, I even arranged where he lived. As soon as Li Congshan went back and said it, Li Yu immediately sent someone to poison Lin Renzhao. This is a typical self-destructive Great Wall.

And who are the people who stay with him at this time? The army of the Song Dynasty was on the opposite side of Jinling City and was preparing to cross the river with a pontoon bridge, Li Yu's most trusted minister Zhang Xun actually said, Your Majesty, I dare to guarantee that it must be fake news, I have read the book for so many years, and I have never seen a book that records the use of a pontoon bridge to cross the Yangtze River, this news must not be true, even if it is true, it must not succeed. Li Yu smiled and said, That's it, it's like a child playing at home, you can't do it really. The imminent crisis made these two monarchs and ministers ignore the past like child's play, if he doesn't lose the country, who will lose the country.

"The three of them became tigers, and the crowd was full of gold, and the bones were destroyed...... Since ancient times, how many idioms and examples have shown how easily we are guided by external things and the views of outsiders. For example, a courtier, although he speaks reasonably, is very unpleasant, and may be disgusting; And the other courtier seems to be extremely loyal, in order to make the king happy for a while, he actually treats national affairs as a child's play, who is loyal and who is traitorous with these two, who should be close to and who is far away, I think the answer must be self-evident. Lin Feng concluded.

"Countless phenomena in reality tell us that we must always keep a clear and fair mind about everything, anything, and everyone. A person must observe the facts and changes in a matter, and a person must observe his words and deeds for a long period of time; The real approach to a policy is to be patient, to debate its essence, and to observe its effects. Okay, that's all for today's lesson. ”

"Respectfully, Mr. Xie Lu Xie Lin." Li Yu and Li Congqian thanked together!
