Zhang Chao, his unusual side was quickly revealed in front of the police.

Yunhai said that most people with mental illness have no more than seven reasons.

First, psychological reasons, people with poor psychological quality are emotionally fragile and nervously sensitive, and they will not be able to forget for a long time when they encounter some small things, and their feelings are easily hurt, which will then lead to autonomic nervous system disorders and produce a series of physical and mental disorders.

Second, physiological reasons. Some people are born with certain functional defects, as well as genetic factors.

3. Behavior

Poor sleep schedules and behaviors such as smoking, alcoholism, and indulgence can also lead to mental illness.

Fourth, the pressure of overload

Today's urban population is surrounded by high-intensity study and work pressure. Being in a high-pressure state for a long time without respite will cause psychological fatigue over time, and at worst induce mental illness.

Fifth, life is forced to aggravate psychological pressure

The burden of family life and the fierce competition at work can easily induce mental illness under the effect of double burdens.

Sixth, the pressure of studying is too heavy

In recent years, there have been more and more cases of mental illness among primary and secondary school students, which cannot but arouse the concern of the general public. These students have to face endless exercises, constant nagging from parents and teachers, and endless exams every day. With heavy expectations, they had to speed up their pace and tense their nerves. Under heavy pressure, these students will inevitably have psychological barriers.

7. Lack of care

Judging from the above analysis, Zhang Chao doesn't seem to be quite compatible, he seems to be a normal person who can't be more normal.

The only thing that makes Yun Hai doubt is the first point, the psychological factor.

After Zhang Chao's marriage to his first wife, why didn't he remarry? Is it because a failed marriage has created a shadow in his heart that makes him afraid of marriage?

However, in an investigation with his ex-wife, it was learned that the divorce was proposed by Zhang Chao.

Zhang Chao's ex-wife Liu Fen said that the two were married on a blind date, and the age of the two of them was not young at that time, so they couldn't talk about any feelings, even if they were old, the two of them lived together.

After getting married, she obviously felt that Zhang Chao was very cold to her, and the two of them were under the same roof, but they were like two unrelated strangers.

His ex-wife said that at first she also understood, after all, the two met on a blind date, and soon after they met, they entered the palace of marriage, and their lifestyle and personality had to be slowly run-in.

After a year of marriage, the two had a daughter.

I thought that after the child was born, the cold relationship between the two people would be better.

Unexpectedly, the relationship between the two has not changed at all.

She has also made noise, but Zhang Chao has taken her indifference to the extreme, every time she is noisy, Zhang Chao doesn't say a word, and goes out of the house directly.

When his daughter was one year old, Zhang Chao filed for divorce and left the house.

Liu Fen didn't get it back, so don't want such a cold marriage.

After the divorce, Liu Fen took her daughter to live in her mother's city, and the two had little interaction in their lives.

In this regard, Yunhai directly asked Liu Fen, would Zhang Chao not like women?

Liu Fen said that she had thought so too, but there was no way to confirm it, and she had never heard of Zhang Chao being entangled with any man.

Zhang Chao is a native of Chunyang City, and his old mother is still alive and well.

What kind of person Zhang Chao is, the old mother naturally knows.

On the first floor of an old building in the old city, Xiao Mo and Qi Nan found Zhang Chao's old mother who lived alone.

The old man is very talkative, and he is naturally surprised that the police come to the door.

Xiao Mo didn't tell the old man the truth, but just said that they were colleagues in Zhang Chao's prison and asked some questions about job promotions.

The old man was happy to hear it, and he couldn't close the conversation box when it was opened.

The old man said that Zhang Chao was good at everything, but he didn't have a family for so many years, and his only granddaughter was in other places, and he had almost no contacts.

When asked why Zhang Chao never remarried, the old man sighed.

"Alas...... It's all my fault, it's me who hurt him. ”

The old man said that Zhang Chao liked a girl when he was young, and the girl seemed to be surnamed Qin, what was the specific name, the old man did not have a good memory, and said that it seemed to be called Qin.

This Qin girl was born very beautiful, and lived on the fifth floor of this old building with her mother, and that girl was also interested in Zhang Chao, and she should be regarded as a talented man and a woman.

But this girl is good at everything, but she doesn't have a serious job, she works as a salesperson in the mall during the day, and sells clothes at night in the night market.

Zhang Chao was working in the police station at the time, and he could be regarded as having a particularly decent job.

At that time, Zhang Chao's parents were resolutely opposed to the two being together, mainly because of the girl's work and family.

Moreover, his mother is still sick all the year round, and there is only such a daughter in the family, if Zhang Chao marries this girl, he will say that he will bear another responsibility, a drag.

Of course Zhang Chao didn't do it, and said a lot in front of his parents, either marrying a girl from the Qin family or being a bachelor for the rest of his life.

Zhang Chao's mother saw her son's resolute attitude, so she changed her strategy and turned to attack the Qin girl, so that the Qin girl was far away from her son, it was impossible for a family like them to marry a girl with no education and no decent job to enter the house.

I didn't expect this trick to work, and it didn't take long for the Qin family to move.

Where it moved, no one knows.

Zhang Chao looked for it like crazy later, but the girl surnamed Qin seemed to have evaporated from the world, and there was no news.

In the following years, Zhang Chaozhen, as he said, did not see the blind date arranged at home, and turned a blind eye to any girl.

The old couple can't go on like this for a long time, otherwise his old Zhang family will have to be broken.

The old couple changed their minds, Miss Qin is Miss Qin, it's better than being a single person for a lifetime, the two of them also asked someone to find it, but they just didn't find the girl of the Qin family.

Zhang Chao changed his mind or later Zhang Chao's father was seriously ill and died soon after, in order not to let the old man leave regrets, Zhang Chao listened to his mother's advice and married Liu Fen, who was on a blind date.

But after getting married, the relationship between the two was not very good.

After the death of Zhang Chao's father, Zhang Chao insisted on divorce.

Zhang's mother said that this was her son's revenge on her, and he and his beloved girl were separated at the beginning. Although she bitterly persuaded Zhang Chao not to divorce for the sake of her children, Zhang Chao did not listen to the persuasion.

And said a word to the mother.

"I said that I would either marry her or be a bachelor for the rest of my life, and if you want me to get married, unless it is her."

Zhang's mother was a little helpless in the end, saying that Zhang Chao complained to her parents because of Miss Qin's affairs, and later took the initiative to ask Ying to be transferred to work in prison.

For so many years, although the No. 3 Prison was not far from Chunyang City, he only returned to Chunyang City on major holidays.

The old mother said that the last time she saw Zhang Chao was during the Spring Festival.
