Chapter 930 The Returnee's Notes 4
The old lady didn't give Xie Ning the option to refuse, but only told her to be prepared. She didn't give her any verbal instruction, probably intending to lead by example and let Xie Ning learn by herself.
However, he did throw Xie Ning an old blue-covered book. Although it was worn, there were no signs of insect damage, indicating that it had been well-cared for.
"This month, you should memorize this book and learn to do math. Someone will pick you up at 3 p.m., so remember to set an alarm."
After saying that, the old lady went back to her room. Except when she had to go out or when guests came to visit, the old lady basically stayed in her room.
Xie Ning wasn't sleepy, so she turned on the light to read because the room had small windows and was dimly lit.
But perhaps because it was noon, the room was much warmer than it had been in the morning.
The blue book was entirely written in traditional Chinese characters, which posed no difficulty for Xie Ning to read, since she had used traditional characters for writing during the Republic of China era. However, the contents of the book surprised her somewhat.
Because this is just a simple introduction to Yin and Yang, the Eight Trigrams, and the Sixty-Four Hexagrams.
Xie Ning wasn't an expert in this area, but she did have some understanding of it. After all, it was a necessary knowledge point in the previous world, not to mention that she had been working with the Imperial Observatory to improve instruments.
As the saying goes, Taiji gives rise to Yin and Yang, Yin and Yang give rise to the Four Symbols, and the Four Symbols give rise to the Eight Trigrams. The horizontal line on the Eight Trigrams is the Yang line, and if it is broken in the middle into two short horizontal lines, it is the Yin line. The Yang and Yin lines are arranged and combined in eight ways to form eight different celestial phenomena.
The eight trigrams lead to the sixty-four hexagrams, and the sixty-four hexagrams lead to the next, just like a permutation and combination math problem that can be explored endlessly.
What cannot be ignored is the pattern.
Xie Ning had studied and memorized the texts of the sixty-four hexagrams in the Book of Changes, but he had not delved into their meaning.
Just as Xie Ning was engrossed in his calculations, the alarm clock beside him started beeping. It was 2:45 a.m., and someone would be coming to pick him up soon.
After glancing around, Xie Ning emptied his backpack and put in a folding umbrella and a folding fruit knife.
The backpack provided cover and made it easy for her to retrieve other items.
The old lady was already sitting at the square table outside, while the black cat was squatting on the table licking its paws. When it heard Xie Ning come out, it only glanced at her. It was a cool and aloof little cat.
Xie Ning noticed that new red incense candles had been lit in front of the Laozi statue. The smell of wax lingered around, but it wasn't unpleasant, nor did it give people a stuffy feeling; rather, it had a pleasant and peaceful atmosphere.
As soon as the clock on the wall pointed to three o'clock, the roar of a motorcycle engine sounded outside. The sound was very loud, and Xie Ning guessed that the motorcycle was probably not of very good quality.
However, what awaited the two was not a motorcycle, but a small tricycle.
To be honest, this was Xie Ning's first time riding in a tricycle like this, and because the road conditions were bad, it was very bumpy. The old lady was fine, but Xie Ning's stomach was already churning.
Unconsciously, I quietly pressed the acupoint to reduce the urge to vomit.
The tricycle driver in front of me was smoking with one hand and driving with the other, while also chatting loudly with the old lady.
The old lady outside wasn't as silent as she was at home. Xie Ning listened to the two talking in their dialect without saying a word, because she wasn't very familiar with the local dialect yet, and the less she said, the less likely she was to make a mistake.
Judging from her accent and some of her memories, she was probably in Guangdong Province, and based on the economic situation of the town she had seen, it was probably a remote area of Guangdong Province.
It takes about fifteen minutes to drive from the town to Fengyi Reservoir. Xie Ning didn't pay attention to the scenery along the way. Only after getting off the bus did he feel a sense of lightness.
The driver drove the tricycle like a race car, even drifting when turning, while the old lady sat steadily.
Xie Ning's legs were shaking a little when she got out of the car. After all, she was really not used to it. Even if she could bear it mentally, her body's reaction was a little hard to control.
I still need to exercise more.
