Guangzhou is a capital city of Guangdong province. I remember last time, there was a thief stealing money from a people in the bus. The bus driver noticed this situation, he closed the door and called the police. It means he protected people's money. Even you are alone when you are got trouble, you also can all the police in hotline 110, they you will find you and help you.   Si cuan is a place where earthquake often appear in China. Scientists developed a program to help people. It can countdown of 10 seconds advance to warn people. You can know this information from your computer, cell phone, even where you live where there will be a broadcast to inform you. It give a few time to people for save themselves.   Young people go for work around 8:00 am every day. Many people go to bus station and subway this time. But you will also find that many old people go for tea by transportation in the same time. Young people need to go for work on time, otherwise they will lose money because of late. If old people can go out late a little bit will be much better, because they no need on time.   In last year, government announced a new rule about garbage. We need to sort the garbage to 4 types, such as recyclables, kitchen waste, hazardous waste, and other waste. We putted all garbage in the same box before. now we need to know which kind of garbage is belong which box, then put it in.

Oct 8th 2020 In China, if you lose your ID card that will have many troubles. You might lose money of your bank account and you might be in debt.   Firstly, if you want to ask a service of bank, you need to provide your ID card. It can prove that who you are. The bank need to confirm that it is you ask the service. They will check the picture and other information from the ID card. Why they do like that? I saw a news before, someone took the ID card that someone else had lost it and go the bank, he took all the money then left. When the owner of the ID card received the message from the bank, He was told that he had been taken all the money by himself. He just found that he lost the ID card and the bank card. The owner realized other people who reset the password with his ID card and took the money. He called the police. In this case, the bank has a big problem about this. So, the bank need to more be careful to confirm all the information of user.   Secondly, once you lost your ID card, you should apply for it as soon as possible. Some bad guys will take you ID card to bring money from bank or private loan company. If the bank and the agency are negligent that you're going to have a lot of debt. Recently I lost my ID card and bank card. I got very nevus because I can`t apply the ID card immediately. I need to get the original of a contract of new company which provide to the government certification center, then they will accept my application. My friend told me that it will makes me have more trouble before I got the new ID card. I made a call to hotline of government which ask about this. They told me that it is not a problem to me. If other people take my ID card to do illegal things, I don`t need to bear the legal responsibility. That makes me relieved. But I told myself that I have to more be careful next time about my ID card.

The world is one step closer to having a totally secure internet and an answer to the growing threat of cyber-attacks, thanks to a team of international scientists who have created a unique prototype which could transform how we communicate online.

What I understand: Dr Siddarth who led the project at QET Labs said that the quantum has a big change and make it become to more realistic proposition. Buildin

Researchers develop simple method to 3D print milk products II To tackle these limitations, the research team from SUTD's Soft Fluidics Lab changed the rheological properties of the printing ink and demonstrated DIW 3D printing of milk by cold-extrusion with a single milk product -- powdered milk. The team found that the concentration of milk powder allowed for the simple formulation of 3D-printable milk inks using water to control the rheology. Extensive characterizations of the formulated milk ink were also conducted to analyse their rheological properties and ensure optimal printability. What I understand: The research team changed the 3D printing of milk by cold-extrusion - powdered milk. They also found that the concentration of milk proder allowed use water to control the rheology of 3D-printable. "This novel yet simple method can be used in formulating various nutritious foods including those served to patients in hospitals for their special dietary needs," said the lead author and Ph.D. candidate from SUTD, Mr Lee Cheng Pau. What I understand: The lead from SUTD said that this simple method can be use in many kinds of food, including serve to patients in hospitals for their needs. "Cold-extrusion does not compromise heat-sensitive nutrients and yet offers vast potential in 3D printing of aesthetically pleasing, nutritionally controlled foods customized for individual requirements," added Assistant Professor Michinao Hashimoto, the principal investigator of the study. What I understand: Assistant Professor Michinao also said that the cold-extrusion does not damaged the nutrients and offers potential in 3D printing of controlled foods.

Researchers develop simple method to 3D print milk products Researchers from the Singapore University of Technology and Design (SUTD) developed a method to perform direct ink writing (DIW) 3D printing of milk-based products at room temperature, while maintaining its temperature sensitive nutrients. What I understand: Researches from SUTD which find a way to 3D print milk products. 3D printing of food has been achieved by different printing methods, including the widely used selective laser sintering (SLS) and hot-melt extrusion methods. However, these methods are not always compatible with temperature-sensitive nutrients found in certain types of food. For instance, milk is rich in both calcium and protein, but as these nutrients are temperature sensitive, milk is unsuitable for 3D printing using the aforementioned printing methods which require high temperature. While the cold-extrusion is a viable alternative, it often requires rheology modifiers or additives to stabilize printed structures. Optimizing these additives is a complex and judicious task. What I understand: 3D printing of food can print it in different way which by SLS and hot-melt extrusion. But these methods are not usually match other types of food. Even milk has rich nutrients, but it is not good to use by 3D printing mothods which require high temperature. when the cold-extrusion is work that will require to print structures.

Sep 14th 2020 II I would like to introduce the difference between Bluetooth headsets and normal headsets. You will find the difference from the function, the sound of quality, and the different in appearance. Firstly, Bluetooth headsets are more easily than wired headset. Bluetooth headsets use Bluetooth as connect and provide the digital. The cable of headsets are different. I broke some wired headsets before because the cable which is entangled. I always need to change a new one. And Bluetooth headsets have no cable, you can easy to wear. But the normal headsets no need to worry about the battery and need charge it. The most important is the Bluetooth headset can use in a formal occasion. When you going to a business speech which use Bluetooth headset can effectively avoid many accidents, because it is easily to high the headsets than a general one and more suitable for office activities. Secondly, Bluetooth headsets look more beautiful and have smart functions, normal headsets dont have smart functions. Most popular in the market is the Bluetooth. It’s a big selling point. Usually the Bluetooth headsets are use with the smart phone. It compares the normal headsets are more diversity. Normal headsets use to control the voice usually. In addition to these funtions, Bluetooth headsets can also help people to make a call or cut off the call. For this function from the current market, the normal headsets not as popular as Bluetooth headsets. Thirdly, the sound quality of normal headsets is mostly better than Bluetooth headsets. The production of two are also different. Bluetooth headsets used Bluetooth for data transmission, the data might be delay. But the normal headsets wont happen this situation. The data will not lost, so the sound quality of normal headsets is mostly better than Bluetooth headsets. Some people thought that use the normal one to play the video game is a good choice.

Sep 14th 2020 Carbon-rich exoplanets may be made of diamonds As missions like NASA's Hubble Space Telescope, TESS and Kepler continue to provide insights into the properties of exoplanets (planets around other stars), scientists are increasingly able to piece together what these planets look like, what they are made of, and if they could be habitable or even inhabited. What I understand: TESS and Kepler are provide insights into the properties, scientists piece the planets how look like, what they are made, and can settle down or not. In a new study published recently in The Planetary Science Journal, a team of researchers from Arizona State University (ASU) and the University of Chicago have determined that some carbon-rich exoplanets, given the right circumstances, could be made of diamonds and silica. What I understand: A new study showed that the ASU and University of Chicago were give the circumstances to made diamonds and silica. "These exoplanets are unlike anything in our solar system," says lead author Harrison Allen-Sutter of ASU's School of Earth and Space Exploration. What I understand: The lead of Harrison said that these exoplanets are unlike anything in our solar system. Diamond exoplanet formation When stars and planets are formed, they do so from the same cloud of gas, so their bulk compositions are similar. A star with a lower carbon to oxygen ratio will have planets like Earth, comprised of silicates and oxides with a very small diamond content (Earth's diamond content is about 0.001%). What I understand: When stars and planets bulk compositions are similar. A star will have planets like Earth with a very small diamond content.2
