In fact, Mrs. Sun is too poorly educated and she doesn’t know that there are different blood types.

Old Mrs. Sun's child did not develop well in the womb and was born weak and sickly. This was one of the main reasons why she changed the child at that time.

When the child was over two years old, he was hospitalized due to illness. Ding Hai's mother learned that the child's blood type was different when tested at birth.

The couple was hospitalized and needed a blood test. When they saw the report, the blood type was wrong and they thought the hospital had made a mistake. They did another test, and the blood type was still wrong. Only then did they know for sure that the child was not theirs.

After careful reflection, we all agreed that the only possible time for the change was during the few days of hospitalization after childbirth. This was not an easy matter to investigate.

First, I returned to the hospital where I gave birth and questioned the doctor and nurse who delivered the child. When I found nothing, I searched for two other women who had given birth in the same ward. I finally found them by following the address they'd registered as hospitalized. But the child's appearance was unmistakable. Now over two years old, they both look very much like their parents.

This clue was broken, there was really no clue to find. Later, after searching for more than half a year, Ding Hai's father went to the battlefield to support CX, and gradually put the matter aside.

Ding Hai's parents' actions weren't irresponsible; rather, they had no other options under the circumstances. Who wants to be separated from their own flesh and blood? They certainly tried their best to find him, but then, due to the war and the needs of the country, they had no other options.

In this way, Old Lady Sun’s child grew up in Ding Hai’s real home, but was he living a happy life?

His life was not happy at all. Not only was he unhappy, he was also timid, selfish, cowardly, and his academic performance was not very good.

He started bullying his classmates when he was in the third grade. In the fifth grade, he secretly learned to smoke and was seen by Dong Guanyu who was on vacation. After being rewarded with a belt and fried pork, the boy learned to obey in public and disobey in private. Later, many bad habits he developed became hidden.

He also used Ding Hai's real name: Dong Yuanchao.

Ding Hai's mother, Li Cuiwan, was a descendant of a prominent family, originally from Shandong. Her mother died during childbirth. Motherless, she was raised by her father. Shortly after Ding Hai's birth, her grandfather passed away. Despite her health, Li Cuiwan, who had just finished her confinement, traveled thousands of miles back to her hometown.

Ding Hai's father is the youngest son of the third branch of the Dong family, an old aristocratic family in Kyoto. His name is Dong Guanyu. He joined the army at the age of 18 and met Li Cuiwan when he was 20 years old while performing a mission in Shandong.

At that time, Li Cuiwan was only 18 years old and went to see Baotu Spring with several female classmates. Dong Guanyu and several comrades who had finished their mission also took time to see Baotu Spring. That was how they met for the first time.

As they were both young people, the two groups quickly struck up a conversation. Dong Guanyu was immediately drawn to this pretty, cheerful Shandong girl. They exchanged addresses and began writing letters. After chatting for a long time, they finally became romantically involved, a perfect match.

Dong Guanyu had been close to his eldest wife's brother, Dong Guanliang, since childhood. When Dong Guanliang's marriage was in trouble, Dong Guanyu offered his full support in finding his daughter. Later, Dong Guanliang was framed, subjected to big-character posters, and then sent to a labor camp in just four days—an astonishingly quick process. All relatives shunned the situation, and no one informed the eldest wife, unwilling to get involved. It was he who contacted his eldest brother, who worked in the three northeastern provinces and was considered Dong Guanliang's closest cousin.

Actually, Ding Hai and Dong Guanyu don't look particularly alike. A son takes after his mother, so he looks like her. But isn't that amazing? Dong Yuanchao also looks quite similar to Li Cuiwan. Otherwise, even if the children were swapped as children, they would still be recognized.
