Being slicky? or just be myself. I remember that when I was asking my American friend of his opinion on Chinese people a few years ago when we are in Shanghai, he told me a word called slicky. I didn't quite understand what does he mean by that, and he explained to me that it was sort of like the combination of a person who is handy, street-smart, or even a con-artist. It was just a bit of thought from him after we've been trying to get a bargain at the fake market, get a driver's license, get a scooter bike from a local shop, and even an argument on our missing Peking duck at a restaurant and some illegal shit. We did so many things in Shanghai, and my friend is the type of guy who always carries a piece of a gun in the U.S. His hometown was ranked top 3 dangerous cities in the U.S, life is not easy there according to him. I guess he kind of found some similarities of Shanghai compared to his hometown where you either become a guy that nobody wants to mess around or a loser. And the impression of Chinese people to him are just that, hardworking, get shit done, but if you are stupid they will rip you off for sure. Back then, I was always told by my family and relatives that I was too honest, and they always looked at me with sympathy in their eyes, like I will be the one that cannot survive in China. For a long time, I always wanted to be a badass, con-artist, or the character like in God-father. It was my personality that intervene me to be the most dominant or charismatic person in my group, but now I kind of accept the fact that maybe being an introvert is not so bad especially after finish watching the Ted Talks of The Power of Introverts. Maybe I don't need to care about other people's opinion, I just need to accept who I am.

Some thoughts of Australian Music Industry. I have been reading some articles and industry report of the global music industry this afternoon in the library. I have some interesting foundings that I would like to share with. Firstly, Australia is the 6th largest market in the world in 2017 while China ranked only 12. Secondly, the increase of digital download and streaming services has seen a significant leap from the previous year counting for 40% increase globally while the physical record section has dropped by 60%. Lastly, 40% of Australians nominate music as their number one passion. As I currently living in Sydney at the moment, I do notice that many people have been using Spotify from youngster to my co-workers and shop owners. Many of them are paid users. It is reasonable for me that due to the strict copyright law and licensing regulation, it is common and less annoying to pay for the music instead of download legally from the internet. However, back in China, even though the market size is much bigger than Australia, most people would take it for granted that music should be free to listen. I have also sensed that the music industry is very sophisticated, one of my favorite music radio station in Sydney have been immensely supportive towards local artist with 50% of their music played on air are produced by Sydney artist. This is just an example of the Australian music industry's healthy and organic environment in a nutshell. In the end, thanks to the benefit of digitization which bring prosperity to the music industry.

D o you think cardless society is realistic and why? What are the advantages and disadvantages? The topic of whether cardless society is realistic or not has been a controversial debate, while some people think it is has a negative impact on our society, but I am convinced that cardless society is a must of the development and it certainly has more advantages than disadvantages. I do admit that there are some arguments suggesting cardless society would be an incubator for cyber-crime. There are more cases where personal information security and credit card fraud has been reported. In addition to this, senior people may find it very struggling as they are not used to the new method of payment, for instance, they may have trouble using Uber instead of getting a taxi like the old-fashioned way. However, there is no doubt that our society has witnessed an enormous change of consumer behavior from buying stuff at retail store in the shopping center to shop online with a few clicks and the goods will be delivered to your home address. Some countries have already become cardless such as China, 90% of the daily money transactions have been done on the smartphone apps including pay utilities, medical care, food and groceries and etc. With the reduction of the cash economy and tax evasion, cardless society has definitely increase transaction clarity. Furthermore, thanks to the technology that the convenience we embracing now would inevitably help boost the economy.' In conclusion, I think the advantages have outweighed the disadvantages, and there is no doubt that our society would be beneficial from the cashless revolution.

Whether a competitive environment in school would bring excellence and need to be encouraged? A competitive environment in school and university would bring excellence and need to be encouraged. To what extent do you agree or disagree? There has been a heated debate on whether a competitive environment in schools and universities would bring excellence and need to be encouraged. Although some believe that competition would help students with their academic achievement, I am convinced that bringing severe competition may not be a good idea for students. Firstly, I do admit that schools and universities are places where students learn knowledge before they step into the crucial business world. A competitive environment would be encountered sooner or later, so it would be beneficial for students to adopt this environment at a relatively early age. Also, a more competitive environment challenge students work harder in their studies in order to discover their hidden talent or achieve greater academic success. However, there are numerous reasons why schools and universities should not be an extremely competitive place, for example, schools should also be a place for students to make friends and help with each other instead of seeing each other like enemies, in addition to this, a competitive environment may stop some students from going to school or even learning. According to a recent research, 15% of the students who study in a very competitive environment may suffer a wide range of mental health problems including anxiety and insomnia. Not only students' physical health but also mental health should be taken into consideration when making schools into a competitive place. In conclusion, I think schools and universities should not make the environment a very competitive place for students, schools should not only be a place for students to learn knowledge but also a place for them to make friends and stay healthy physically and mentally.

If it is worthy of exploring outer space There are many debates on whether it is important for human being to expand our knowledge and discover the outer space especially the cost of time and money are extraordinary. In my opinion, exploring outer space would solve enormous global issues and it is the ultimate mission for all human kinds. Firstly, there are some tough issues which we all facing now including climate change, over population, pollution, global warming, and the list can be going forever. None of these issues are easy to solve. According to some recent report, global warming is now the most devastating issue on the planet which would possibly wipe out every creature on earth make it an inhabitable planet. It will be inevitable for human to seek for shelter on other planets in the universe and eventually it would be the only solution for us. Secondly, curiosity and spirit of adventure has always been the vital components that driving us to rule the planet as the most intelligent creature ever existed on the planet. Looking at the human history, we only have been on the planet since ten thousand years ago which compared to the existence of the universe is just too little. There are too many unknown out there, and it will be our ultimate mission to explore as many planets as we can during the limited time we have on earth. In conclusion, it is vital for us to explore the outer space despite the cost of time and money.
