The market watchdog(市场监督部门)in northwest China's Xi'an has started a survey in a complaint that a woman's newly bought Mercedes-Benz car has engine oil leaks(泄漏). The incident has attracted wide attention after a video of a woman sitting on top of a Mercedes-Benz while weeping and arguing with salesmen went viral online. In the video posted on Weibo by a net friend on April II, the woman said she found an oil leak when she was driving the car home from the 4S store. After she drove the car back, the trader claimed(宣称)the car had passed all tests before it was sold. She was told she couldn’t get her money hack nor change a new car for her. All that the trader could offer was to change the engine. The CLS300 car cost around 660,000 yuan.($98,445).

The customer met with officials from the market watchdog of Gaoxin District on Saturdav, requesting full maintenance(维修)history of the car and an independent lest by a third-party，Shaanxi TV Station reported.

Mercedes-Benz issued an announcement on its Weibo account on Saturday，saying it was sorry for the customer's "unpleasant experience". The company has sent a team to Xi’an to help solve the problem. Li Yong, an official with the market watchdog of Gaoxin District in Xi’an, told cruest.com that they learned about the incident online. They are still surveying the incident. They will punish those who are responsible if anything illegal is discovered.

If we’re already working alone at home, why do we always think of working with our heads similarly down in a public setting?

Of course, Covid-19 has made impossible the stay in a cafe for long, and meanwhile made remote work normal part of life. As we begin another year living with a pandemic (流行病), we might wonder why, when things settle down, we should bother going back out to work in public, only to work independently with our heads down — something we’re already doing at home now.

But putting on your noise-lessening headphones to work at your desk is actually different from doing the same surrounded by other people buzzing over your shoulder. There are many ways coffee shops awake our creativity in a way offices and homes don’t.

A 2012 study published in the Journal of Consumer Research showed that background noise in a place like a cafeteria can actually increase your creative output. The idea is that if your attention is slightly taken away from the task at hand by stimuli (刺激), it improves your abstract thinking ability, which can lead to more creative ideas.

Another study from 2019, which had similar findings, centers around what’s called “stochastic resonance”: originally observed in animals, it’s the phenomenon in which just the right amount of noise benefits our senses. And while the amount varies, audio stimuli in the background also help us improve decision making. So, the jazz, light conversation and banging coffee grounds aren’t an annoyance — they could help you come up with your next grand work.

There’s also the fact that in a cafe, we’re surrounded by people who’ve come to do the same thing as us, which acts as something encouraging. A 2016 study backed up this idea noting “simply performing a task next to a person who made a lot of effort in a task will make you do the same”.

The well-known Tsinghua University and Peking University held graduation ceremonies (典礼) on the same day this year. The presidents of the two universities delivered excellent speeches at the ceremonies as they used words, phrases or ways of expression that are very popular on the Internet currently. At the same time, graduation speeches by other university presidents were also under the spotlight for the same reason. Their speeches were warmly welcomed by students as they contained many fashionable words today, such as “floating clouds” (meaning “too small and of little importance to mention”) and “gelivable”   (meaning ”very helpful”) . In the speeches , these university presidents recalled campus life together with students and finally moved all the audiences. They were very different from the usual run of lectures.

Many university presidents have changed their regular manner of making speeches at graduation ceremonies from an advising and preaching (说教)mode to a more fashionable and funny way. They try to use those words popular among young people in their speeches.

In the past, university presidents’ speeches were criticized for being too standard and lacking emotion. Now, they use fashionable words in their speeches, reflecting they are starting to adopt more everyday attitudes to students. The use of these new expressions has triggered a heated discussion. It focuses on the question of whether university presidents should speak in an informal way at graduation ceremonies.

Supporters who are in favor of the university presidents, new manner of making speeches consider it good to build close ties with students by using the youth’s own words even during the formal ceremonies. Opponents argue the new ways have no practical value or significance for education but are merely to please those leaving university.
