Talk show host Cui Yongyuan recently blasted the idea of limiting private cars to reduce smog, saying that the harm of vehicle exhaust to the environment is as meager as a fart to a residential community. He said he had concluded through investigation that trucks carrying construction waste cause more pollution. His claims aroused a wave of ridicule and questioning of the Ministry of Environmental Protection online.

To professionals, the methodology of Cui looks like a joke. Most well-educated people know that scientific research requires a large database of samples and meticulous analysis, rather than making conclusions through seeing. The acknowledgement and online support of Cui is typical of Chinese public opinion.

The striking remarks of celebrities are just like bubbles in the cyber world, popping up from time to time. The speakers have the image of youth mentors and speaking for the ordinary people, and the topics are mostly specific problems. They target the government and the system, as criticizing the authorities has become shorthand for boasting of a social conscience.

These criticisms don't provide constructive suggestions. Complaints usually don't cause trouble, but if a large number of people believe them, it might cause misconceptions of social problems thus sway government decisions.

We have to admit that the public discontent toward the government has been fueled by genuine complaints. Everyone is concerned about the environmental deterioration, which is why Cui's remarks spread.

Cui's sense of questioning and investigative attitude are worthy of applause, as the government legislation needs public participation. On the other hand, the conclusions by Cui also need review.

Celebrities acquire power from their various social identities, and how they behave at those positions is mostly a matter of tailored image. They are face-to-face with the public on Weibo and Wechat, thus a better sense of social responsibility and self-discipline are needed in order to fulfill their influence on the society.

Remarks that are not in line with public opinions would be picked out and paraded online, while those feed the public appetite would be cheered even if they are flawed. This has effectively encouraged the recklessness of celebrities.

The Internet hasn't stopped seeking the truth, despite the longer period it takes. The circulated materials online are always traceable, thus a remark that win you applause today may well become a humiliation in the future. Media professional should watch their own words and stop making featherbrained remarks. This will accelerate the process of truth and contribute to the construction of a society with integrity.
