　　At the age of 22, Liu Lu is barely old enough to shave and may indeed still have peach fuzz on his face instead of whiskers, but his youth has not prevented him from becoming the youngest professor in China．Last week, Zhongnan University in the central Chinese city of Changsha appointed Liu to a professorship and also awarded him one million yuan in recognition for his solving a complicated math problem called the “Seetapun Enigma”．It's not unusual for young people such as Liu to do great things．Most great poetry and many great scientific and mathematical discoveries have leaped from the minds of young geniuses．We only have to think of the poetry of Byron, the inventions of Edison and the theoretical breakthroughs of Einstein．

　　Unlike Liu, however, most geniuses have to wait a long time to receive the recognition and rewards of their achievements．So Liu's skyrocket to the top has ruffled some feathers in academia and on Weibo．The critics believe that a professorship should only be given after long years spent in the academic trenches writing research papers and teaching in classrooms．In other words, professors should have to pay their dues．

　　For the most part, though, people have supported Liu's appointment．They believe that creativity, innovation and individual genius should be encouraged in China．If China is to grow and prosper, it needs young minds like Liu's．

　　But that raises another question：Is Liu a good role model? Liu was only a mediocre student in high school and university, and, as yet, does not have a postgraduate degree．Will others see Liu's success as an excuse to ignore the traditional school system?

　　When we are young we all think that we are special; budding geniuses just waiting to flower．While it may be true that we are special, not many of us are geniuses．For most of us, the knowledge and discipline that we learn in school will be the basis for our success in later life．We should accept that, but schools should also accept the “specialness” of individual students and do more to encourage students to develop that specialness．After all, as Liu has shown, having a little peach fuzz on your face doesn't mean you can't do great things．

　　Tired of all the pushing in supermarkets? Fed up with waiting in endless lines to pay for what you have bought? Angry at wasting time in traffic jams only to find no parking spaces when you eventually arrive at the store? If this is you, then online shopping is the answer to your dreams of trouble-free(安全可靠的)shopping, Or is it?

　　Online shopping brings its own challenges．Here are a few things to bear in mind when browsing(瀏覽)various websites．The claim(主張)made by online sites is that shopping online is a safe and secure way to make purchases．The evidence challenges this．In any case, you only have to be the victim of fraud(詐騙)once to experience all the problems that come with this form of stealing．Use only sites that have a trusted history and an excellent reputation．

　　Another problem is the appearance of items in reality is often quite different from what you see on your computer screen．This might not be a problem if you are buying washing up powder but could be a major disappointment when that beautiful blue dress you ordered turns up in green．Also, product descriptions are sometimes simply untrue Perhaps the wisest plan is to purchase items where design and color are not essential to customer satisfaction．

　　Some even argue that online shopping indirectly contributes to global warming．Yes, your car can stay parked but how are online goods delivered? Often by some large van porting out carbon monoxide and adding to our already desperate traffic problems．You are also by now becoming increasingly irritated(使煩惱)by the fact that the delivery is late and you have wasted the leave from work you have taken to receive it!

　　Without question, online shopping is here to stay and it has its benefits．However, perhaps it is not as wonderful as some of its supporters claim it to be．
