Mr. Nguyen Van Toan and Mrs. Le Thi Lan (both 58 years old, Hanoi) have two sons named Thanh (34 years old) and Thao (30 years old). In the neighborhood, they are considered a model family because of their family traditions, happiness, and success in marriage and children.
Mr. Toan and Thanh both work in the road and bridge sector but in two different agencies. They often go to supervise construction projects in many localities. By chance, during a business trip to Tuyen Quang, Thanh saw a man who looked like his father carrying a basket full of food coming out of a local stall.
He silently moved closer and secretly observed. The young man was extremely surprised when it was his father. Mr. Toan walked to the end of the alley and then entered a small gate. The twin boys ran out of the house to greet him, shouting loudly, "Hooray, dad's home."
Thanh was silent. He understood that his father had another woman and children.
Returning home after the business trip, Thanh did not dare reveal this secret to his mother.
A month later, he asked his father to meet him at a coffee shop and told him everything he had witnessed. After hearing this, his father was forced to bow his head and confess the whole truth.

Mr. Toan said that during a field survey 6 years ago, he met and worked with Mai - an employee of the district's land office. They both liked each other from the first meeting. Mr. Toan liked her because of her quick manner, polite, proper speech, and cute face. Mai was passionately in love with the calm, quiet personality of the man from Hanoi.
Mr. Toan told Mai the truth about his marital status. Even though she knew he had a wife and children, she was willing to accept any conditions to live with him.
A wedding party without a representative of the groom's family quietly took place in the countryside where the girl lived. The clandestine marriage continued smoothly until Thanh discovered the truth.
In front of his children, Mr. Toan said he felt truly loved and respected when he was with his concubine. Through his father's comments about his concubine, Thanh believed that the two twins were his siblings, but he still wanted scientific evidence to confirm it.
After some research, he learned that only DNA testing could accurately determine bloodline. Before taking the twins for testing, Thanh went to hospitals to ask doctors for advice on DNA testing.
The expert instructed him to take hair samples from the two children and himself for testing to determine whether the baby was the biological child of the father or not. The result was that Thanh and the twins were not related by blood. Holding the results in his hand, Thanh was stunned and speechless.
He doubted the accuracy of the testing process so he went home and secretly took his father's hair to the testing center to make two samples. One sample was from Mr. Toan and the twins, the other sample was his own hair and his father's.
The test results showed that Thanh and Mr. Toan were not related by blood, and that the two twins were his biological children. Holding the DNA test results in his hand, Thanh collapsed in the lobby of the DNA analysis and genetic technology center.
That same evening, Thanh's family had an urgent meeting. At this time, Mrs. Lan confessed that she had kept the matter a secret from her husband and children for over 30 years.
When they first got married, Mr. Toan often went on business trips, while Mrs. Lan stayed home and secretly had an affair with her ex-lover. Thanh was her child with that man, not Mr. Toan's.
The continuous tragedy caused the conflict between the family members to reach a climax. In the end, they decided to divorce. Mr. Toan went to live with his second wife, Mrs. Lan stayed in that house with Thao, and Thanh decided to rent a house of his own.
According to Ms. Nguyen Thi Nga, Director of the Hanoi DNA Analysis Center, DNA paternity testing is the most accurate testing method today. If the DNA samples of the mother, child and suspected father match in each gene, the accuracy of the blood relationship is 99.999% or higher. That means that in fact the man being tested here is the father of the child.
If the two DNA samples of the child and the suspected father do not match in two or more genes, then this man must be 100% excluded and the possibility of being the child's father is 0%.
DNA testing using a set of 16 genes has a high accuracy of up to 99.999%. If you want to test DNA, you only need 10 hairs with roots, or fingernails or blood samples.
