After listening to Han Qing talk about what happened in the Han family back then, Su Nian and the others all looked at each other, not knowing what to say, which was really unlucky!

"So, now it's just me in the house!" Han Qing sighed, looking like a cynical young master again.

Tang Xin rubbed her little face in shock, she looked at Su Nian, then at Han Qing, and stammered, "If you suspect that Su Nian is your sister, why don't you take a paternity test?" ”

Han Qing sneered: "My parents are missing, who will do the paternity test?" My grandfather and sister are both related, and they are male relatives, so I can't check this! ”

It turned out that there were really a lot of people in the Han family who recognized their relatives over the years, which led to Han Qing becoming an expert in this area.

Parents and children can do a paternity test to determine whether they are related by comparing the similarity of the DNA.

If the parents are gone, and there are only grandparents and grandchildren, the appraisal is called kinship, and according to the technical level at that time, it is impossible to prove kinship.

If it is the grandfather and grandson who need to be identified, these two male relatives have a Y chromosome, and this chromosome can be compared at this time, but unfortunately Su Nian is a girl and does not have a Y chromosome, so she can't compare it with Grandpa Han, and it is impossible to determine whether the two are related by blood.

Because of the comparison of genetic similarity, it is necessary to reach more than three points of identical identity before it can be considered that the two identifiers are related by blood.

The ancestors and grandchildren inherited from generation to generation, trying to find three similar points, with the technical level at that time, could not reach it at all.

In the same way, Han Qing and Su Nian's paternity test is also not clinically significant.

Su Nian is also very clear about these things, and she studied this matter carefully in order to do a paternity test with Su's father and Su's mother.

Explain these things to Tang Xin clearly, it is almost nine o'clock.

Chu Beichen looked at the sky, and said to Han Qing: "Anyway, there is still something to gain today, I will take Su Nian home, as for Tang Xin, I have to trouble you to send it back to school!" ”

Of course, Han Qing couldn't ask for such an arrangement, but he would not let go of any opportunity to tease Tang Xin, so after listening to Chu Beichen's suggestion, Han Qing looked at Tang Xin condescendingly, "Little Tang Xin, I have contributed a lot today, not only to call you to come immediately, but also to send you back to school!" ”

Tang Xin blushed, you must know that what Uncle Han did to her at school last time made her very angry to this day, but looking at today's situation, I am afraid it will not work if Uncle Han does not send her back.

She was just about to nod, when she saw a staff member walk in, holding two boxes in his hands, "This is a meeting gift from the chief ~ to the two young ladies, please hand it over to Minister Han!" ”

Han Qing took it and opened the box to show everyone, only to see that there were exactly two white jade safety buckles inside, the jade was delicate and shiny, "This is what my grandfather got in his early years, there are no girls in the family, he has been saying that these two jade buckles are wasted, and now they are just right for you!" ”

Han Qing closed the lid and handed it to Su Nian and Tang Xin respectively, he was very clear about his grandfather's intentions, and it was reasonable to give Su Nian one, as for Tang Xin, this was the first girl he brought home, and it was estimated that his grandfather regarded her as his future granddaughter-in-law.

Su Nian and Tang Xin excused themselves for a while, and seeing that Han Qing insisted, they also accepted the gift.

"Su Nian, don't worry, the matter of tracking down the cufflinks is on me, and I will look for a suitable candidate tomorrow!" Han Qing promised to pat his chest and promise.
