The Sun family's guess turned out to be correct. Their family has not been doing well in recent years, and it is indeed the work of Sun Aimin's second grandfather.

However, the Master Yiyuan who induced the Zhan Jinhua couple to exchange for Yuan Jie and Sun Aimin's child was not arranged by the Qin family.

No matter what, the news that the Sun family donated ancient books to the country finally made the Qin family give up completely.

The Qin family now only had the demented old man Qin and Qin Xingzhou. Qin Xingzhou was only thirty years old, and his wife Zhan Tiehua was a college student, two years older than him.

After graduating from university, Zhan Tiehua joined the health system. In the next twenty years, he made a lot of convenience for the Zhan family to carry out "business".

The child-swap case was exposed twenty years later. The reason why the Sun and Yuan families had a hard time was closely related to Zhan Tiehua. She had used her power to create obstacles for the Sun and Yuan families.

Although Old Man Qin was a gambler, he had learned cooking from his elders since he was a child and had some cooking skills. After Qin Xingzhou's father's accident, it was impossible for him to live entirely on the compensation.

Old Man Qin taught Qin Xingzhou's mother some recipes for making cooked food. Later, his mother relied on selling cooked food to make Qin Xingzhou's childhood relatively affluent and to support Qin Xingzhou to finish high school.

When Qin Xingzhou grew up, he took over the delicatessen business and got to know Zhan Tiehua.

Zhan Tiehua often visits Qin Xingzhou's delicatessen. One reason is that Qin's delicatessen tastes good, and another reason is that Zhan Tiehua has a crush on the handsome Qin Xingzhou.

It can be said that there are no ugly people in the Qin family, including people like Sun Aimin who have some Qin family blood. None of them does not look outstanding among the crowd.

Although the Zhan family members are not as good-looking as ordinary people, they are rich and powerful, so it is easy for them to find a few sons-in-law to marry into the family.

This was the case with Qian Jincai and Qin Xingzhou. These two sons-in-law were outstanding in appearance and had indeed improved the appearance genes of the Zhan family.

For example, Qian Longfei is smart and handsome, the most outstanding among all the children in the Zhan family. Unfortunately, he was lost on the train some time ago and has not been found yet.

Zhan Jinhua and Qian Jindou, who are currently incarcerated awaiting trial, are still unaware of the disappearance of their beloved youngest son. If they knew, how would they react? Would they consider this karma?

Another example is Qin Xin, the seven-year-old daughter of Qin Xingzhou and Zhan Tiehuasheng. She's already a beauty, sporting the Qin family's signature large eyes and a delicate demeanor. They also have two sons: their eldest, Qin Junyi, five, and their second, Qin Junchen, three. Both are chubby and adorable.

As a public official, Zhan Tiehua might lose her job if she has more children than allowed. She studied hard and entered the health care system, all of which were planned in advance by her family. If something unexpected happens as a result, it would be more trouble than it would take.

Moreover, the Zhan family has always valued male offspring more. After giving birth to Qin Xin, Zhan Tiehua and his wife did not rush to register her household registration, but quickly became pregnant again and gave birth to Qin Junyi.

In this way, Qin Junyi became the only child registered in their household at that time, while Qin Xin never had a household registration and was considered an illegal resident.

After the Zhan family established connections with the household registration department, they were able to legally register multiple households. Zhan Tiehua and Qin Xingzhou had a second son, Qin Junchen, and registered him on another household registration, but there was still no place for Qin Xin.

Seeing that Qin Xin was old enough to go to school, they found a family surnamed Zhang in Zhanjiazhuang and registered her household with the Zhang family. The name she used was "Zhang Ling".

At that time, the Zhang family already had three children. Their daughter Zhang Miao is now four years old, and their sons Zhang Shuai and Zhang Jun are twins, now three years old.

In order to avoid fines for having more children than allowed, the Zhang family had triplets. Zhang Miao was thin and small, not even as tall as her two younger brothers who were one year younger than her. This was because the Zhang family had been starving her since she was born, making sure she was neither starving to death nor full, in order to prevent her from growing taller and prepare for having twins with her later brothers or sisters.

Afterwards, Zhang's father and mother quickly became pregnant and gave birth to two sons as they wished. They also registered Zhang Miao and his two sons.

The reason why Zhan Tiehua and Qin Xingzhou chose to adopt their daughter into the Zhang family was mainly to exploit loopholes in the family planning policy.

The policy at that time stipulated that people with rural household registration, whose first child was a girl, could have a second child without paying a fine if the interval between the two children was more than four years.

The two of them discussed it and decided that if they wanted to register their daughter under their household registration, since they both had city household registration and Zhan Tiehua had a formal job, they would have to use the Zhan family's connections to apply for a new household registration.

But using connections isn't free; each household must pay the contact a fee of 1,000 yuan. The Zhan family was willing to spend money to open multiple households to facilitate their business. If they had to open a new household for their neglected daughter, they wouldn't have felt it was worth it, as it would have cost 2,000 yuan for two people.

The other families in Zhanjiazhuang who didn't have a suitable candidate were required to pay a fine for having more children than allowed, and naturally, Zhan Tiehua and Qin Xingzhou had to pay for this. At the time, the fine for having more children than allowed was several thousand yuan, more expensive than getting a new household registration.

The Zhang family is poor, has many children, and has a rural household registration. The child's registered age is exactly four years younger than Zhang Ling's, which just meets the requirements of the two-child family planning policy.

In the end, they only gave the Zhang family 200 yuan to solve their daughter's household registration problem. On the Zhang family's household registration, Qin Xin's name was "Zhang Ling", the woman who deceived Sun Aimin and Yuan Jie with twin sons 20 years later.

Zhang Ling has Qin family blood, so it is not surprising that her children look like members of the Sun family and their kinship can be detected. This is also the main reason why she was able to get away with it easily.

Since her household registration was in Zhanjiazhuang, she had to go to school in the countryside. Therefore, Qin Xin no longer lived with her biological parents after she started school. Instead, she lived in the Zhan family and was taken care of by her grandparents, the village chief Zhan Dayou and his wife.

Ever since Qin Xingzhou became the son-in-law of the Zhan family, he had been roped into their trap. Like Zhan Jinhua's noodle shop at the Mafang Railway Station, the delicatessen he ran harbored a dark secret: it served as a transit point for abducted children.

However, the situation has been tense recently, so the Zhan family has suspended this business, but Qin Xingzhou's delicatessen is still open as usual.

Now, inspired by Qian Jinling's experience, the Zhan family has found a new way to make money: surrogacy. They found two surrogate mothers for Qian Jinling, and she's very satisfied. The two girls have successfully conceived, and she readily transferred the final payment of 10,000 yuan.

This matter is relatively risk-free. Even if you are caught, you can say that it was consensual between the person involved and the surrogate mother, and it is at most a moral issue.
