The inspectors said: “Compared with middle-aged people, many of the difficult-to-defend ticket evaders are young people after 90.†Because many people in this group are either arrogant or refuse to cooperate after they have been discovered. I can imagine that the child who evades votes every day is also a clever man who is deaf after playing with this uncivilized social environment. In the first two days, some media exposed a 15-year-old middle school student in Nanjing to paint a “travel here†on Egyptian relief more than 3,000 years ago. The student’s actions were also obviously tainted by the adult’s uncivilized tourist behaviors. .
It is time to reflect on education. The news often reveals that all sorts of odd questions in the early examinations, such as young ascension and small ascension, cannot even be made by genuine doctors, and there are "Olympiads" that destroy childhood. However, children obviously lack the "Odyssey" that is really necessary: ​​the Olympic ethical competition. Public moral education is an important part of citizen education. True moral education should not be "super moral," and "Odyssey" should start from not evading votes or damaging cultural relics.
With the growing requirement on taking
advantage of environmental pollution and energy well, this oil-gas
recovery vacuum pump will be applied to this field widely.

The Shanghai Metro operator conducted a flight evacuation inspection and rectification operation on May 29th and many “tribes†were arrested. After being arrested, the performance of the parties differed: Some did not send the words, and they were dumb and dumb. There were also "Sisters" crying for mercy for a moment. A schoolboy admitted that he not only evaded the ticket today, but also "every morning, they go out to school." The reason given by the children for their daily flight evasion is that “My parents gave me five bucks a day, two bucks for breakfast and three bucks for a subway ticket, but I didn’t have enough breakfast for two bucksâ€. On the beach, there are actually still relying on fare evasion to eat enough?
