Although there is enough space in the Zhao Mansion now, it can easily accommodate two entourages. But Eryang still asked his servants to settle elsewhere as usual. They put on narrow-sleeved Songjiang cotton robes and gauze caps, and lived alone in the house to serve their master.
When Zhao Hao handed the gifts to his uncle for storage, and the two of them had lunch with their master, they couldn't help but ask:
"Master, when will we start class?"
"You can do it at any time." Zhao Hao said with a smile. The two of them were about to cheer, but they saw him stretching and saying, "I'll start after I take my lunch break."
"Master, have a good sleep" The two of them then remembered that Master had a habit of taking a lunch break.
They had no choice but to wait patiently for Zhao Hao to get up.
In order to pass the agonizing time, the two of them carefully cleaned the main room and study room where Zhao Hao lived.
After Er Yang polished the floor furniture and looked at the shiny tabletop, they both felt that their impetuous moods had finally calmed down.
¡°Senior brother, doing housework is really a good way to practice.¡±
"Yes, during the time when I was home, I didn't do any housework, and I became restless"
Wang Wuyang nodded in agreement, and suddenly heard the door of Zhao Hao's bedroom opening.
"Master"
The two of them, who had looked calm just now, rushed out of the study room.
"Can we start class now?"
??~~
Zhao Hao did not shirk anymore this time, and ordered Gao Wu to carry the large wooden box he put in the study, and took his two students out of Zhao's house by car.
He took advantage of the three people to distract the fans and slipped out of the back door in a car. He didn't dare to rejoin them until they were out of the Jubao Gate.
Then the carriage went all the way south, passed through Nancheng Gang, and came to the picturesque Yuhuatai.
Yuhuatai is the commanding height in the south of Jinling City, facing Dabaoen Temple in the distance. The star observatory of Qintian Prison in Nanjing during the Ming Dynasty was set up here.
The carriage slowly went uphill along the path between the bamboo forests, and the forest was quiet. Thousands of green bamboos stood tall and tall, and the autumn wind blew, undulating and rippling, making people feel like they were in the middle of the waves.
Eryang could not help but be secretly excited and whispered:
"Master is indeed a master. He chooses the place where he gives lectures so carefully."
"Yes, before there was Wang Yangming's "Tianqiao Preaching" and "Mountain Discussing Flowers", and now there is my master "Bamboo Forest Teaching" and "Yuhua Discussing Tao", it can be said that they complement each other"
"We must remember Master's every word, deed, and action, record it when we go back, and publish a "Traditional Records" in the future"
"It's just that Master is younger than me. We're afraid we won't see the day when "The Record of Biography" comes out"
Zhao Hao was initially pleased with what he heard, but it became clear that the two of them were getting more and more ridiculous. He was so angry that he glared at Er Yang and said:
"No nonsense!"
"Yes, Master!" Eryang was afraid that he would offend the Master and not allow them to go to class. He quickly shut his mouth and looked at his nose and heart until the carriage stopped.
??~~
The carriage stopped at the top of the slope. The three masters and apprentices got out of the carriage and saw a five-foot-high tower standing in front of them.
On the outer door of the balcony, there is a mottled wooden sign with the words "Star Observation Platform" written on it.
The door to the observatory is ajar and no one is guarding it. Gao Wu opened the door, and the three masters and apprentices went in and took a look. They saw that the courtyard was full of weeds and the walls were mottled and had long been in disrepair.
In the eighteenth year of Yongle, after Chengzu moved the capital to Beijing, the Nanjing Qintian Prison existed in name only, and no one has been to the observatory for an unknown period of time.
The four of them searched for a long time before they found an old soldier who was guarding the tower. They gave him two taels of silver. Without saying a word, the old man opened the tower and sent the four to the top.
Then without asking any questions, he went to the wine shop under the Yuhuatai to get a drink.
General Gao put down the wooden box on his back, and then retreated to the next floor to guard so that no one would disturb the master and apprentice's teaching.
Zhao Hao opened the wooden box and found a folded blackboard inside. He unfolded the blackboard and placed it on the rusty armillary sphere beside it. Then he used chalk made of lime and wrote five words on it - 'Open' See the world'!
¡°Open your eyes to see the world!¡±
Wang Wuyang and Hua Shuyang read out the title in unison.
Zhao Hao¡¯s first lesson in the first year of Longqing in the Ming Dynasty finally began.
Under the sunshine of the afternoon, Wang Wuyang and Hua Shuyang looked at Zhao Hao standing with the backlight, and felt that the master's whole body was covered with a layer of sacred light and shadow.
"Do you still remember what happened on the day Shu Yang became a disciple?" Zhao Haofa asked."Remember, after it rained that day, a rainbow appeared!" Hua Shuyang immediately replied excitedly: "It can be seen that my apprentice is a disciple and is fulfilling destiny!"
"Nonsense, the rainbow is a bad omen" Wang Wuyang curled his lips. He didn't have a sense of celestial phenomena when he became a disciple, so he was naturally unhappy.
"Don't talk nonsense!" Zhao Hao glared at the two of them and said, "Let's start with the rainbow that day."
After a pause, he asked: "Do you know what happened to Hong?"
"Everyone says that a rainbow is a dragon sucking water." Wang Wuyang replied, and Hua Shuyang also nodded. This is also the common understanding among the public at this time.
"Really?" Zhao Hao smiled faintly, picked up the bamboo cup, took a sip of water, and sprayed the mist against the setting sun.
As soon as Er Yang saw the mist, there was indeed a colorful rainbow looming.
Wang Wuyang couldn¡¯t help but exclaimed: ¡°Is there a dragon inside Master?¡±
"Nonsense."
Zhao Hao rolled his eyes and sprayed water mist again. In the mist, the rainbow loomed again.
Hua Shuyang suddenly slapped his thigh and said excitedly: "I remembered it. "Mengxi Bi Tan" said that a rainbow is the shadow of water in the sun. It exists when the sun shines and rains. It turns out that what Shen Kuo said is right."
"Shen Kuo is Shen Kuo after all, and his knowledge is far beyond that of the world." Zhao Hao sighed and said solemnly: "The second half of his sentence is right. But the first half is wrong - the rainbow is not the shadow of water, but the shadow of the sun."
"Sun Ying?" Er Yang said in unison.
Then he saw Zhao Hao pick up the blackboard and block it on the small window. The tower suddenly became dark, and only a beam of sunlight shone in through the hole reserved on the blackboard.
Zhao Hao took out a prism made of East China Sea crystal from the box. The beam of sunlight hits the mirror and refracts to the wall nearby.
Wang Wuyang and Hua Shuyang were stunned when they saw a rainbow-like colorful ribbon appear on the opposite wall!
"Red, orange, yellow, green, blue, indigo, purple" Hua Shuyang read out the order of the seven-colored lights in turn, and couldn't help but exclaimed: "The shadow of the sun is exactly the same as the order of the rainbow!"
"Master, what's going on?" Wang Wuyang asked in confusion: "Why does a rainbow appear when the sun shines on the water mist and the three-sided crystal?"
"Because sunlight is originally composed of these seven colors." Zhao Hao replied in a deep voice: "So anything that can make light diverge can produce a rainbow."
"Then why do we usually only see white light?" Eryang asked in unison.
"Because the seven colors are mixed together." Zhao Hao tried his best to use a language that the two of them could understand, and replied slowly: "But the properties of the seven kinds of light are different. Once refracted, they will disperse separately and become what you see. The rainbow arrived.¡±
As Zhao Hao spoke, he took out another equilateral prism and placed it upside down on the line projected by the previous prism. After a slight adjustment, the colorful light gathered again and projected white light on the wall. ¡
"Master is right, the sunshine is indeed colorful!" Eryang suddenly slapped his thigh, feeling that he was being led into the gate of the new world by Master!
Open your eyes to see the world, it¡¯s true!
But this first lesson has just begun
