Chen Xu has been thinking about one thing in addition to studying recently, when he first met Han Yidao, Meng Xiangyu introduced: She and Han Yidao were born on the same day, the same month, and the same year, and they were born in the same delivery room. Is it possible that the two of them were held by mistake? But one of the biggest problems is that a boy and a girl, the gender of the child should be told to the mother when the child is born, right? Chen Xu racked his brains to recall, and remembered that once Han Yidao said that Meng Xiangyu's personality was a bit like Li Zhilan, and he ran all the way to the black. These things kept coming to Chen Xu's mind, making her a little unsettled. Chen Xu thought about it and suddenly had an idea.

Liu Jiaxin was bored wandering around the campus, and Meng Xiangyu was too difficult to get along with, always moody. I was careful, for fear of provoking her, but the more I tried to please her, the more counterproductive it was, and it was too annoying. At this moment, I suddenly saw Chen Xu coming towards me. Liu Jiaxin immediately greeted her, "Hey, Chen Xu, I haven't seen you for a few days." Chen Xu was also unusual, and said with a smile: "Sister Jiaxin, how are you doing lately?" I've heard that PhD studies are boring, and you spend all day in the lab, right? ”

Listening to the title of "Sister Jiaxin", Liu Jiaxin had some mixed tastes for a while, and when she played with Chen Xu when she was a child, Chen Xu always called her that. The two little girls used to be good friends, and they would share delicious food together. When did it change, did she think she picked up the tatters and smelled or did her grandmother not let her pay attention to Chen Xu? Liu Jiaxin smiled a little unnaturally, "Graduate school is indeed more boring than undergraduate, there are fewer classmates, and everyone is busy with themselves." It's basically a dormitory unit, but my roommate is higher than my grade, so I don't get along. ”

Chen Xu was holding a few books in his hand, as if he had just returned from the library. Liu Jiaxin asked, "Where are you going?" Chen Xu moved his neck, "After sitting in the library all morning, my back hurts and my neck stiffens, and I want to go to the artificial lake to take a walk and relax." Liu Jiaxin hurriedly responded, "I'll go with you, it just so happens that I'm fine today." The two of them walked together in the direction of the artificial lake.

Liu Jiaxin was in a trance for a while, the current Chen Xu should have played with him when he was a child, and the one who picked up garbage in the garbage heap all day must not be, there must be a deviation in memory.

Two people sit on a bench by the lake, basking in the warm autumn sun. Liu Jiaxin is not a quiet person, and she couldn't hold her breath after a few minutes, "Hey, Chen Xu, let me tell you, it's too difficult for my current roommate." It was like someone owed her eight hundred hangings. It's too hard for me. Chen Xu snorted coldly in his heart, and said lightly: "Senior Sister Meng is a cold fan, but she is okay. And helped me before. ”

Liu Jiaxin saw her speaking for Meng Xiangyu, and she was upset at the time, "Hey, why don't you distinguish between good and good people?" Is she okay? Last time, she took me to see a woman and asked me about you, isn't this a stab in the back? "Chen Xuxin said, you are the one who handed the knife. She slandered in her heart, but she said, "Is it? I have no grievances with her, what are you doing here? Liu Jiaxin was very satisfied with Chen Xu's reaction, "It's not good, how can there be such a thing." Oops, you don't know, it's too depressing to be in a room with her. We have a research group, I don't dare to propose to change the dormitory by myself, I heard that she has driven away several roommates before, I am careful every day, it is too embarrassing to be kicked out and still in a group. Alas—"

Chen Xu said as if unintentionally, "Senior Sister Meng is so individual?" What kind of blood type is she? Liu Jiaxin said disapprerovingly: "Now whoever still judges personality based on blood type depends on the constellation!" Chen Xu said as if he had never seen the world: "What my classmate said two days ago, how can people with different blood types have such personalities, I heard her say it quite accurately." Liu Jiaxin thought for a while and said, "Don't say it, it makes sense." Meng Xiangyu is blood type AB, and when I used to take biology class, the teacher joked that blood type AB was selfish, which really meant a little bit of fun. ”

Chen Xu found out Meng Xiangyu's blood type so quickly, she was so excited, she didn't worry about confirming it again, "Are you sure?" Liu Jiaxin swore an oath, "I'm sure, a few days ago she asked me to clean the dormitory, I thought about tidying up the cabinet drawers by the way, and saw that there was a blood donation certificate, I opened it curiously, it was Meng Xiangyu's, and it was clearly printed with AB blood." As a result, Meng Xiangyu was still anxious, blaming me for rummaging through her things. I hurriedly said that I thought it was pulled down by someone before, and for this matter, she pulled my face with me for several days. Chen Xu got what he wanted, so he comforted Liu Jiaxin a few words without pain, and then said that he was going to find his classmates and left.

Chen Xu reasoned as he walked, it is possible to give birth to a child with AB type with the blood type of Han Fa and Li Zhilan, and what needs to be known now is the blood type of Meng Xiangyu's parents. Han Yidao is type O blood, if Meng's father and mother are blood type A and blood type B, they can give birth to a child with blood type AB and a child with blood type O, so it is impossible to determine whether it is a mistake. But one of Meng's father and mother has type O blood, if they are both type A blood or both type B blood, it is certain that Meng Xiangyu is not their biological child. Chen Xu thought about it, worked his blood type first, but he really couldn't get into Meng Xiangyu's dormitory by getting into a relationship with Liu Jiaxin, got her hair, and then went to Han Hui's beauty salon to get Li Zhilan's hair and do a paternity test for them. She has been wandering around the neighborhood for several days in order to "meet" Liu Jiaxin. Today can be said to be very successful. Let's do it!

On Saturday morning, Chen Xu accompanied Wu Sixian to go to the small park to sit after buying vegetables, saying that the weather was slowly getting colder, and he couldn't come out to sit every day in the future, so he could sit for a while while the weather was good today. Chen Xu stared at the building opposite, she remembered that Grandpa Meng's life was very regular, and his old man would come out in a few minutes. I hope that today is no exception, Wu Sixian is sitting next to him, and from time to time people he knows will come to say hello, but Wu Sixian, who was busy greeting, did not notice Chen Xu's strangeness.

As Grandpa Meng walked out of the unit door and walked towards Jiexin Park, Chen Xu finally breathed a sigh of relief, and then became nervous again. Grandpa Meng walked into the park and greeted the neighbors and old colleagues he knew one by one. Chen Xu stood up, and when Grandpa Meng came over, Chen Xu bowed and said hello first, Grandpa Meng was kind and kind, and said to Wu Sixian with a smile at the moment: "Old Wu, this kid has a good eye." This girl looks like a good and well-bred child. Chen Xu hurriedly said modestly beside him: "Grandpa Meng, you have won the prize, I am blood type B, and my personality is particularly in line with the statement on the Internet about the personality of people with blood type B." Grandpa Meng smiled, "In the end, it's a child, and you still believe in these!" Originally, Grandpa Meng was going to come over to say hello and then go elsewhere, but Chen Xu asked him to sit down. Chen Xu asked Wu Sixian seemingly unintentionally, "Grandma, what blood type are you?" Wu Sixian replied, "I also have blood type B." Chen Xu smiled and said, "No wonder I'm so close to you!" Wu Sixian and Grandpa Meng both laughed. Chen Xu asked Grandpa Meng, "Grandpa, what blood type are you?" Grandpa Meng said happily: "I am blood type O. As soon as he finished speaking, Chen Xu hurriedly patted his ass, "Type O blood is fraternity, selfless, and helpful." Grandpa Meng laughed, "This kid is really good at talking." Not to mention anything else, type O blood is a universal blood transfusion, my family Lao Liu and I are both type O, I used to help my colleagues with blood transfusions, and there was no obligation to donate blood before, they all sell blood, colleagues sometimes need to use blood, and they are afraid that the blood seller will be sick, so Lao Liu and I sometimes go to give blood transfusions. At that time, the comradeship was comparable to that of brothers and sisters! Chen Xu was so excited that his heart was about to jump out, Grandpa Meng and his wife are both blood type O, then his children must all have blood type O, no matter what blood type Meng Xiangyu's mother is, as long as it is Meng's father's child, Meng Xiangyu should definitely not be blood type AB. I don't know if it's a psychological effect, Chen Xu looked at Grandpa Meng carefully and found that Han Yidao's nose looked very similar to Grandpa Meng's nose, but it didn't look like anything else. Chen Xu was so happy that he would smile from time to time, and Grandpa Meng looked at Chen Xu and liked it very much, "This girl is good, good-looking, good-tempered, sensible, polite, not like our family Xiangyu, who is stubborn, and I don't know who the child's temper is like." Alas! ”
