This is an old man over seventy years old, about 1.7 meters, dressed in a gray retro robe, with crane hair and a childish face, with a strong medicinal fragrance all over his body, and he knows at a glance that this is a Chinese medicine master.

After reading the prescription, the old man asked with doubts, "Sir, who prescribed this prescription?"

Yang Chengzhi smiled, "Old man, I prescribed this prescription, I don't know what problems you have." Yang Chengzhi has always adhered to the teachings of Old Man Yang and respected every old man.

The old man heard Yang Chengzhi say that the prescription was prescribed by the young man in front of him, his face was full of surprise, he just looked at the prescription, the handwriting on the prescription was vigorous and powerful, there are several medicinal materials listed above that only the elderly Chinese medicine can know, he never thought that this ancient prescription was prescribed by the young man in his twenties in front of him, so the old man had a lot of interest in Yang Chengzhi.

"Little friend, dare to ask you where you came from, where this prescription comes from, and what its effect is, my old man is clumsy and can't see it."

Seeing the old man asking, Yang Chengzhi hurriedly said: "Old man, this recipe is from a Chinese medicine remnant book left by my grandfather, which treats patients who have become dementia due to shock and stimulation."

"Dare to ask Xiaoyou, your grandfather's surname is big, maybe my old man knows", the old man asked lightly.

"My grandfather's surname is Yang, his name is Yang Tieshan, a mountain villager, you will never know him."

The old man frowned and thought for a long time, but he didn't think of any Chinese medicine doctor surnamed Yang. He shook his head and said, "I haven't heard of this name yet, you can see from the recipe left here that your grandfather is a Chinese medicine master, when will you let the old man know this Chinese medicine master."

"My grandfather is often on the road, and I haven't seen him in years, and I'm afraid the old gentleman will be disappointed."

"That's a pity, dare to ask Xiaoyou who you use this prescription to treat you, I see that the medicine you caught is still missing a few flavors."

"This prescription is for my mother's illness, my mother was frightened many years ago, and my grandfather has a little stock of a few medicinal herbs that are missing, but it is enough, thank you old man." After speaking, Yang Chengzhi carried the medicine bag and greeted Zuo Jianhua, and Zuo Yumei and Wang Haiyan left Tongrentang.

The old man saw Zuo Jianhua who left with Yang Chengzhi, and he was stunned, Zuo Jianhua didn't know the old man, but the old man knew him, the old man was invited to Zuo's house to see Zuo Yuxia's illness, and he saw Zuo Jianhua who left in a hurry after the old man Zuo's cigarettes and wine at Zuo's house.

The old man knew that Zuo Yuxia, the daughter of the Zuo family, was frightened and demented, from Yang Chengzhi's words just now and Zuo Jianhua who accompanied him, the old man secretly said, "Could it be that this young man is the child of the Zuo family who has been lost for many years, and I will go to the Zuo family tomorrow to have a look."

Yang Chengzhi grabbed the medicine and returned to Zuo's house with Zuo Jianhua and a few others. As soon as he entered Old Man Zuo's house, Yang Chengzhi was startled, and the medicine bag in his hand almost fell to the ground.

In the house of the old man Zuo, in addition to the old man Zuo, there was an old couple and three middle-aged men and women who were about the same age as the old man Zuo.

When these five people saw Yang Chengzhi carrying the medicine bag into the house, their eyes were staring at Yang Chengzhi, so Yang Chengzhi was startled when he saw this scene.

When the old man Zuo saw Yang Chengzhi enter the house, he said to the old man: "This is the child of Yuxia and Guozheng who have been separated for many years, you can see that he and Guozheng are just like a mold."

Old Man Zuo pointed to the pair of old men and said to Yang Chengzhi, "Chengzhi, this is your grandfather and grandmother."

Hearing the old man Zuo say that the old couple was his grandparents, Yang Chengzhi's heart trembled, the old man of the Zhou family, the old lady is here.

The old lady said with trembling hands and a trembling voice: "This is my poor grandson, who looks exactly like when Guozheng was young, come and show grandma."

Yang Chengzhi put down the medicine bag, walked to the old lady and knelt on his knees, and called "grandma" softly.

When his grandmother came out, Yang Chengzhi's eyes were red, and he finally had relatives today after being lonely for more than 20 years.

The old lady heard Yang Chengzhi call her grandma, with tears in her old eyes, she caressed Yang Chengzhi's delicate face, choked up and said: "Good boy, you are suffering, come and sit next to grandma, and have a good conversation with grandma."

Yang Chengzhi got up from the ground and sat beside the old lady, the old lady took Yang Chengzhi's hand and said, "Old man, look at Chengzhi, what a handsome child, Guozheng and Yuxia gave birth to a good son."

Yang Chengzhi looked at the old man beside the old lady, the old man was in his eighties, his body was slightly fat, the sparse hair on the top of his head was gray, his face was ruddy, and he was dressed in a decent Tang suit.

He called softly: "Grandpa, the unfilial grandson has given you a greeting."

Old Man Zhou's eyes burst into tears: "Good boy, grandpa can see you, there are no regrets in this life, but the national government can't look at you," As he spoke, Old Man Zhou's tears finally rolled down.

Yang Chengzhi stood up, sat down next to Old Man Zhou, reached out to touch the old man's teardrops, and said: "Grandpa, don't worry, I will definitely cure my father, I will treat my mother first in the past few days, and I will go over to see my father in a few days."

"You will still see the disease, didn't your grandfather say that you went to college and learned software, I haven't heard that you have studied medicine", Mr. Zhou said in surprise.

"In-laws, Cheng Zhi is the little miracle doctor that Sun Cannon found for us, and Sun Cannon's life was saved by Cheng Zhi", Old Man Zuo said proudly.

"Grandpa, I learned medicine from my grandfather when I was a child, but my grandfather didn't let me show it in front of people, so people didn't know that I knew how to heal,"

"Your grandfather is a strange man, and he doesn't let him spread the rules of this profession if he has medical skills," the old lady said softly.

Old Man Zhou took Yang Chengzhi's hand, pointed to the three men and women sitting on the sofa and said, "Chengzhi will introduce you to them, these are your father's brothers and sisters."

After being introduced, Yang Chengzhi knew the identities of the three men and women who came with the old man and his wife.

A man in his fifties, with a kind face and a special resemblance to the old man, is his uncle Zhou Guoan, who is the mayor of Yanjing City.

The other man, who was less than fifty, with a slightly thin face and a pair of glasses, was his second uncle, Zhou Guocheng. A military commander of a military region in Yanjing.

The woman is a little similar to the old lady, her face is full of heroism, watching him cry constantly, she is the sister of her father Zhou Guozheng, Zhou Wenying. He is the president of Yenching University of Political Science and Law.

The three brothers and sisters heard their father call them, saying that they had found Zhou Guozheng's long-lost son, and the three brothers and sisters immediately put down their work, hurriedly went home, asked their parents, and returned home, the old man told them that their lost child was in the Zuo family, so the three of them accompanied their parents to see the children of the Zhou family who had not seen them for more than 20 years.

Yang Chengzhi got up and greeted the three brothers and sisters of the Zhou family one by one, the three brothers and sisters of the Zhou family looked at Yang Chengzhi, who was dressed ordinarily, their eyes were red and they couldn't help but say, Chengzhi, you have suffered.
