Why marriage is so difficult in 21st century?

    Compare with the 18th & 19th centuries, marriage is more typical for everyone.  Every teenager will be asked when will have a marriage while reunited with family during Chinese New Year. Why it becomes lesser and not so popular in the 21st centurry?

     If a man wants to establish a successful and happier marriage, his salary must be higher than average and he must have a house and a car before giving new birth. Starting from 20 centuries, everyone must at least have a master's degree to have a better job which could earn more salaries than the average family.  A person who graduated with a master's degree, the average ages of them normally are 24 years old. Given better salaries, the average age of the man should be over 30 years old. The older the parents' age, the harder it is to bring up a kid for the physical limitations over 30 years old. Therefore so many people choose to give up having a marriage or bring up a child for their marriage.

    Thanks to the pandemic COVID-19, people keep the social distance and less to travel. The marriage issue is not too essential for everyone in this society. Besides pandemics, the global warming issue has influenced many people to lose their families by floods, wire flames, draughts and etc as well. We hope that we can take over over living situation easily, instead of suffering any losses in family members. 

    In my opinion, I can live better without marriage. I need to have more freedom to choose what can I do every morning instead of worrying about other family member's needs in the first place.

Food culture in the future

     As a species, humans are quite curious about themselves. For teenagers, this innate curiosity includes questions about their own bodies and what they need in order to move and function. By building on this curiosity, humans can explore the concept that certain foods are good for a healthy body as they start to consider the relationships among food, movement, and health.

    As this world is about to be full. We must consider the possible effects of eating plants and explore ways to protect the environment by reducing food waste. Is it possible to save the ecosystems for so many people by increasing global incomes, urbanization, and food balance in the world?

Cross section purpose

     In order to examine the defect or structure, the cross-section destructive method is the vital means of inspecting the failure mode or initial point of the defects. The simple guideline is involved in cutting, mounting(potting), and grinding or polishing with abrasive materials.

    Before performing the cross-section, the first step is to determine the interested area or determine the accurate position. Sometimes we would probably spend enormous time to get to the point that we want to. 

but we would, of course, require an aggressive grinding medium which may annihilate the brittle silicon upon contact. In addition to destroying the materials we plan to analyze, we would probably spend an inordinate amount of time (not to mention expense) getting to this point. A better option is to cut the package near to the plane of interest, using a precision diamond saw, and then to encapsulate the specimen for subsequent preparation.
