"Grandma... Grandma....."

Daughter Yu Tongtong immediately pounced, and Liu Huiyan smiled and picked up the little girl.

Liu Huiyan is 45 years old this year, less than ten years older than Yu Dongqing, and she looks more than 30 years old.

This "Mom", the original Yu Dongqing was really a little difficult to say, but now Yu Dongqing only hesitated for two seconds and called Mom with a smile.

Liu Huiyan was slightly surprised, usually Yu Dongqing didn't scream when she saw her, but she quickly regained her composure and agreed gently.

Immediately followed by a burst of complaints: "Look at you, come here, it's too wasteful to buy such a thing!" ”

"It's all for you and Dad, as it should be." Yu Dongqing hurriedly replied.

These are all polite words, but the process has to go, Liu Huiyan hugged Yu Tongtong into the door, Yu Dongqing also followed, put down the gift and quickly closed the door first, and followed behind.

"Where's my dad?" Yu Dongqing asked in a low voice again.

"He's in the living room, you talk carefully, his heart is not very good." The mother-in-law was a little worried, and specially advised.

Yu Dongqing nodded, but his eyes were admiring the courtyard.

Although there are many courtyard houses in Yanjing, they can be divided into three types: large quadrangle, medium quadrangle, and small quadrangle in terms of scale. And the courtyard house of Mingmei's house is the smallest one.

The small courtyard is generally three rooms in the north room, one bright and two dark or two bright and one dark. There are two rooms in the east and west wings, and three rooms in the south room (inverted seat room). Lying brick to the top, ridged tile house. It can live in a family of three generations, the ancestors live in the main house, the younger generation lives in the wing room, and the south room is used as a study or living room.

The courtyard is paved with brick roads, connecting the doors of various houses, there are steps in front of each house, and there is an osmanthus tree in the middle of the courtyard.

Standing in the middle of the courtyard, you can see the silhouettes of the bell tower and the drum tower, which are clearly visible from the light red silky skylight.

The beast's head at the west end of the bell tower's ridge was said to have been shaken off during the earthquake in 76, and only the beast's head at the east end remained, still bent in the skylight. One of the pillars of the wooden hall of the drum tower is clearly revealed, adding a little light and agile charm to the originally overly dignified silhouette.

What a place, Yu Dongqing couldn't help but sigh in his heart.

"Brother-in-law, are you here......" At this time, Mingmei also came out of the west wing, greeted with a smile, and helped Yu Dongqing carry gifts, and secretly pointed to the living room of the north room, signaling that her father was inside.

"Speak softly." Mingmei also whispered.

At this time, Liu Huiyan also put Yu Tongtong on the ground, and Yu Dongqing took her daughter's hand into the living room.

The old man Ming Hanwen was sitting on a mahogany chair with reading glasses and reading the newspaper, and when he saw that it was Yu Dongqing who came in with his daughter, his brows furrowed and he didn't speak.

"Grandpa, grandpa, today is your birthday, I wish you a happy birthday." Yu Tongtong broke free from her father's hand and ran over.

"Good ......" Ming Hanwen showed a kind smile on his face and hugged the little girl: "Thank you...... Grandpa also wishes you a happy day. ”

Yu Dongqing took the opportunity to walk up, took out the box of big red robes from his pocket, and respectfully placed them on the wooden coffee table.

"Dad, today is your birthday, I wish you a long life than Nanshan and a blessing like the East China Sea."

Ming Hanwen just snorted and didn't answer, but his face was slightly surprised when he saw Yu Dongqing deliver the tea.

"Is this a single plant tea?"

"Dad, your vision is really amazing, this is a single tea from Niulankeng in Wuyi Mountain, I bought it from a friend of mine." Yu Dongqing replied respectfully.

"Bothered." Ming Hanwen said a word and stopped mentioning it, but Yu Dongqing keenly noticed that his face softened a lot.

Liu Huiyan and Mingmei, who were outside the door, hid to the side and listened to the conversation between the two in the living room, until now they were sure that Yu Dongqing had passed this hurdle, and the two Weng and son-in-law did not quarrel at every turn as before.

Although her daughter is gone, Yu Dongqing did not look for a woman again, and is still nominally the son-in-law of this family.

A family needs a man who can handle things too much.

The two glanced at each other, and immediately entered the living room with a smile, and the room suddenly became lively, and Yu Tongtong also performed the rabbit dance last night for her grandfather and grandmother like courtesy, which made the old couple laugh from ear to ear.

The four of them chatted for a while, Liu Huiyan was going to the kitchen to cook, although she usually had a nanny, today was her husband's birthday, and her son-in-law came to the door again, so she was ready to cook herself, Mingmei naturally went to help, Yu Tongtong was busy catching grasshoppers in the yard, and finally left Yu Dongqing to accompany Ming Hanwen to drink tea and chat.

As soon as the two women and Yu Tongtong left, the atmosphere in the room immediately became deserted.

To be honest, Yu Dongqing and his old man really don't have much in common, Ming Han's Chinese, Yu Dongqing studied mathematics in college, and now he is engaged in music, and the old man is not very interested in both.

Yu Dongqing is a little interested in ancient Chinese literature, but he dares to make an axe in front of his father-in-law with this bit of ink?

For fear of making people laugh, you must know that my father-in-law is talking about ancient Chinese literature in college.

But today, Ming Hanwen seemed to want to talk a few words, but he took a sip of tea and said slowly.

"Holly, you're in music, there's a five-tone in our ancient Chinese music, you know?"

"Yes, the ancient five tones are called Gong, Shang, Jiao, Zheng, more than 2,600 years ago in the Spring and Autumn Period, in the "Guanzi Diren Chapter", there is a scientific method of using mathematical operations to obtain the five tones of "Gong, Shang, Jiao, Zheng, Yu", which is the famous "three-point profit and loss method".

Yu Dongqing replied very respectfully.

"Heh....." Ming Hanwen was slightly surprised, but he didn't expect Yu Dongqing to know a lot, and he knew "Pipe and Groundworker".

So, he took over the topic: "Whoever listens to the signs of "Pipe and Groundworker" is like a pig's feeling and shocked. Whoever listens to the feather is like a horse in the wild. Whoever listens to the palace is like a cow chirping. Whoever listens to business is like a sheep from the flock. Whoever listens to the horn, like a pheasant climbing on a tree to sing, and the sound is clear ......."

Together with the five tones, there is also the "Twelve Laws", which is also determined by the method of dividing the "yellow bell" sound into 81 equal parts, and using the method of dividing the profit and loss into 12 tones to produce the ...... of the 12 tones.

Ming Hanwen suddenly gushed endlessly, and Yu Dongqing could only listen to him.

To be honest, he also understands these ancient music theory knowledge, how can he have his own father-in-law who cites scriptures and drops his book bag at every turn?

There are clouds in "Purple Cloud Song": "Shangxiao Five Tones and Twelve Rhythms, Immortal Songs Remember the Heart Calendar" Ming Hanwen finally said: "We have a lot of music scores lost in ancient times, such as "Guangling San" and "Pingsha Falling Geese" Many of the scores circulating today are commissioned by later generations, as well as the original songs of the Song Dynasty, which can be sung, but unfortunately only the content of the words is left now. ”

Yu Dongqing nodded.

Indeed, several songs with lyrics from famous Chinese poems in that time and space, such as Faye Wong's "When is the Bright Moon", as well as "Qingping Tune" and "Poppy Beauty", including the rock song "Beacon Yangzhou Road" sung by the reincarnation band, adapted from Xin Qiji's lyrics "Yongyule Jingkou Beiguting Nostalgia".

But that's all modern arrangement, because none of them use the ancient pentatonic scale!

"It's a pity, it's a pity." Ming Hanwen sighed.

Yu Dongqing's heart moved, and he said with a smile: "Dad, I have a song here that is written in ancient pentatones, do you want to listen to it?" ”
