Chapter 723

In the afternoon, Guo Xiang and Li Yuanhang went to catch some mice, put them in cages, and brought some wooden frames to put them in cages.

Then fully disinfect the laboratory, wear protective clothing and inject HIV virus into the mice.

When you come out again, the doors and windows are locked. No one can enter here without permission.

The worn protective clothing shall be placed in the basket on the corridor outside the office and reused after being cleaned and disinfected by the school workers.

The life span of HIV virus in a dry environment in vitro is very short, only a few minutes, and it is extremely resistant to high temperature. It can be killed by more than 70 degrees of water, or it can be easily killed by direct irradiation under ultraviolet lamp.

However, if it can survive for more than ten days in the laboratory culture medium, or it can survive for several days in the body fluid and blood, it cannot leak out with liquid.

After that, Guo Xiang began his laboratory life.

Do some data analysis before the mice don't get AIDS.

Life is in order.

Soon it was November, and the weather in Beijing had begun to get cold.

This weekend, Guo Xiang rested at home. The two small groups put on cotton padded jackets. The whole person was round and cute.

The twins were chasing little Q in the yard. Suddenly there was a knock on the door outside.

Little Q barked at the door and the twins stopped.

Guo Xiang went to open the door and saw Zhang Ling standing outside with a smile. Beside her was a tall, thin young man.

"Sister in law!" Zhang Ling shouted.

"Lingling is coming, come in!" Guo Xiang smiled, called Xiao Q and tied it to the side.

"Hello!" The man on the side greeted Guo Xiang with a smile. His accent was a little strange.

"Hello, Hello, please come in!" Guo Xiang smiled and let people in. He pulled Zhang Ling and asked in a low voice, "is this your object?"

"Yes!" Zhang Ling nodded, a little shy, "I met abroad before."

"ABC?" Guo Xiang asked, no wonder the accent is strange.

"What is ABC?" Zhang Ling asked.

"Er..." Guo Xiang said. May this statement be available in future generations“ Are Chinese born abroad, Chinese of rice origin? "

"Yes, how do you know?" The man was surprised.

"I can tell by the accent." Guo Xiang said.

"That means I don't speak Chinese well." The man looked a little annoyed.

"No, it's already very good, but people who don't grow up in China inevitably have a strange tone. It's very normal." Guo Xiang said hurriedly.

"Introduce it!" Guo Xiang said to Zhang Ling.

"Oh, this is my object, Martin. I met him when I went to the United States to communicate. Since then, there has been correspondence. Recently, his company in the United States has set up an office in China, so he came here to work, and then we were the target. " Zhang Ling said.

He also said to Martin, "this is my cousin, Guo Xiang, a graduate student from Beijing Medical University, and now a doctor in the cancer hospital."

"Hello, nice to meet you!" Martin learned some Chinese, but his pronunciation was strange.

Guo Xiang couldn't help laughing, "come in!"

The two small groups looked at the guests curiously. Guo Xiang said, "call your aunt and uncle!"

"Good aunt!"

"Hello, uncle!"

The two little dumplings shouted and ran inside, shouting, "Dad, Dad, guests!"

Gu Zhennan came out of the room and saw Zhang Ling nodding to her.

Zhang Ling called "cousin" and then introduced Martin to him. Several people sat down in the living room.

Guxide saw that some guests also came out to say hello. Guo Xiang went to make a pot of coffee and came over.

Martin was surprised to smell the smell of coffee. It turned out that people drink coffee in China? He has just come to work here. Everyone else in the company likes tea and few drink coffee.

It seems that Zhang Ling's cousin's family is a little different.

He looked at the courtyard curiously. He had never seen such a quadrangle courtyard abroad. It was very beautiful and had Chinese characteristics.

"Coffee, please." Guo Xiang brought the coffee.

"Thank you!" Martin said hastily.

The two small groups leaned against Gu Zhennan and looked curiously at the uncle with a strange accent.

"Lingling, come and help me get some things." Guo Xiang excuses Zhang Ling to ask her something.

"Hey!" Zhang Ling answered and got up to enter the room with Guo Xiang.

"Really? How do you think of looking for foreigners? " Guo Xiang asked in a low voice.

"Well, I think he's pretty good. And he doesn't care about me... "Zhang Ling was a little embarrassed.

Zhang Ling is no longer in trouble, and has lost a fetus. Many people in China will care. It's probably impossible to talk about it. If you don't say it, you'll make trouble if you know it later. It's possible to say that she cheated on marriage, so it's good to find a foreigner.

Guo Xiang nodded. Indeed, foreigners are relatively open. They generally don't care where they are. As long as they get along well, family conditions are not a big problem for them.

Although he is a Chinese, he grew up abroad and should be more open-minded.

"Have you told him?" Asked Guo Xiang.

"Well, I don't want to hide it. We've been communicating in the past year. Both sides know a lot. He's also talked about his girlfriend before, and he didn't hide it." Zhang Ling said, "but I still want to bring him over to show my sister-in-law."

Guo Xiang nodded, "it's best for both sides to be honest, but they won't quarrel because of this in the future. It's OK to look at people. If you feel good, you can decide by yourself. We can't touch them at ordinary times. "

"Yes." Zhang Ling nodded.

Guo Xiang took some snacks, put them on a plate and took them outside. "Try our snacks and see if you're used to eating them."

"Thank you!" Martin nodded politely.

He took two snacks to the twins next to him. "Hello, children!"

Twins look at Guo Xiang. My mother said you can't eat strangers. Is this OK in your own home?

"Thank you, uncle!" Guo Xiang said.

The twins took it and said, "thank you, uncle!"

"Are they twins? How lovely! " Martin smiled and said, "I want two children in the future."

Then he looked at Zhang Ling. Zhang Ling's face turned red and smiled shyly.

Guo Xiang looks at the interaction between the two and seems to have a good relationship.

"Shall we eat at home at noon? Let you taste the flavor of our capital. " Guo Xiang smiled.

"Well, thank you very much. After I came to China, I have eaten a lot of Chinese food. It's really delicious. I didn't expect so many delicious food. " Said Martin.

"Are you Chinese? Don't you eat Chinese food abroad? " Asked Guo Xiang.

"Yes, but affected by the environment, we are still used to eating western food, which is also convenient to make." Said Martin.

Guo Xiang nodded. Indeed, many Chinese who grew up abroad are almost westernized. Some can't even speak Chinese. It's good for him to say so.

Maybe this is the best choice for Zhang Ling.
