The professor may send a mayor order to change the foot bath store for the library association to claim that it is not reliable diesel generator | diesel generator price / 2012-05-05
Hangzhou, May 5th: "If I became the mayor of Hangzhou, my first order was to change all the foot washing houses into libraries." Lin Shaohua, a professor at Ocean University of China, said in a speech at the Zhejiang University of Commerce and Industry recently that he has caused applause. This paragraph was later sent to Weibo, causing users to clap bricks. The Hangzhou Footbath Industry Association subsequently responded by saying: "It's totally unreliable."
The professor made a virtual "Mayor's Order" and triggered the network
Lin Shaohua, 60, a professor at the School of Foreign Languages ​​at Ocean University of China, is a well-known translator who is familiar with the public by translating many works by the Japanese writer Haruki Murakami's "The Forest of Norway."
This microblogging has triggered netizens to “pause bricksâ€, mainly in two aspects.
The first is to expose "the abuse of public power."
Netizen "Ping II" commented: "What right does the mayor have to decide private economic structure to interfere with the lifestyle of Others?"
Second, this change will result in the waste of laid-off workers and financial resources in the foot bath industry.
The netizen “Potato Brothers A†said that Mr. Lin came to pay footwork workers' wages or severance fees? How many “humble†people are supported by the footbath shop.
Hangzhou Footbath Association disapproved 130,000 people rely on footbath to eat
For this virtual mayor order, the Hangzhou Footbath Association disapproved.
“A full-scale library for the foot bath complex. Where do people with foot bath needs go to spend?†Wang Xinmin, president of the association, looked very angry. “The statement is totally incompetent and nonsense.â€
The association’s secretary-general, Jin Shuhong, also said: “This professor may not understand the foot bath industry in Hangzhou.â€
When you see Lin Shaohua saying that “you can use foot bath staff to train as a librarian on the spotâ€, one of the staff members of the association immediately asked: “A foot bath shop can have thousands of employees. Does a library need so many people? ?"
The foot bath history in Hangzhou also dates back to 1995. At present, there are about 2,300 foot bath shops registered in Hangzhou, and 130,000 people are employed.
"The early Hangzhou foot bath shop was chaotic, poor, and small, and was mixed in the market." Jin Xiaohong said that the Hangzhou foot bath industry now has an industry self-regulatory organization.
On April 26, 2005, Hangzhou Foot Industry Association was established. Three years later, the 2008 Hangzhou Footbath Industry Development Report “Foot Bath Blue Book†interview was drafted by the association. This is the first case in the Hangzhou service industry and even the national foot bath industry.
In May 2010, Hangzhou's service standard specification "Star Classification for Foot Care Enterprise" was issued and implemented. The foot bath enterprise was divided into a low-star and a high-star with a total of five levels, which is also the first in China.
Regarding the current phenomenon of pornography in the foot bath industry in Hangzhou, Kim said that this is a long-term social issue and should not be denied. But overall, the foot bath industry in Hangzhou is moving in a positive direction.
The professor responded: “The foot bath house is just a metaphorical symbol and it is not intended to actually shut down.â€
For this virtual "mayor order," Lin Shaohua himself also said: "Foot pavilion" is just a metaphor of social commons, not intentionally shut down.
According to Lin Shaohua, he gave two lectures at Zhejiang University and Zhejiang University of Technology. When talking about the current Chinese people's fascination with houses, tickets, cars, and wine, they have reached the level of “fetishism†written by Marx. He feels that the lack of spiritual pursuits of the people in the country requires more contributions in the cultural field. This excitedly issued this "virtual mayor order."
He recalled that he once had the only foot bath in a regular foot bath shop in Henan. At that time, he felt "very uncomfortable" and "very uncomfortable" and he hurriedly left after the end.
So, in the face of criticism and denial on Weibo, Lin Shaohua is slightly surprised: "Zhejiang, a talented man, can't understand his metaphor?"
When asked about how to transform the footbath into a library and how to operate it, Lin Shaohua said that he was only a scholar. He spoke to the current social issues with his “book business ethos†in his speech, only symbolically representing the country’s vulgarity. The pursuit and enjoyment, rather than the foot bathhouse that is operated under the law, does not carry out specific research and thinking.
Regarding the accusations of “abuse of power†by netizens, Lin Shaohua smiled and claimed that he was only a virtual mayor and that he did not have the power to talk about abuse.
“Is the foot washhouse low and the library noble? No matter if the occupation is noble or noble, people don’t necessarily have read-only books.†For the metaphor of Lin Shaohua’s metaphor, Ms. Xu, a Hangzhou citizen, still believes that she is not good enough. (Finish)
