In those days, people were cautious indeed if they wanted to voice opinions contradicting the dominant ideology. There were definitely restrictions on "freedom of speech". But even then, I never saw or knew of any technological means being used to monitor people's private lives.

Things have changed dramatically during the past three decades and the practice of "reporting to the organizations" has been abandoned forever. Citizens now enjoy considerably more freedom in saying what they want.

Log on to any Chinese website and you will see all sorts of remarks posted in chat rooms, forums and blogs, ranging from criticism of the government to discussions of sexual experiences. Even printed media frequently carry articles criticizing government decisions. Though, it should be said, such freedom of speech is still different with that defined in the West.

Ordinary Chinese citizens do harbor a number of grievances against the government at different levels on certain issues. But if somebody told them that the government is taking technological measures to peep into their private lives, they would not believe it.

So, let's return to the taxi camera controversy; our foreign friends, such as those mentioned above, may find it hard to believe that most Chinese readers supported the decision to install surveillance cameras in taxis. No doubt they are puzzled as to why so many Chinese people would willingly surrender their privacy in such a situation.

But such is the case.

There are two reasons that account for this:

First, sacrificing individual interests for the sake of the public, or communal, interests is still inherent in Chinese culture. People do not find it particularly irksome to be exposed before a gazing lens during a relatively short ride, when doing so is part of one's duty to society. Second, the current social conditions are not orderly and safe enough for people to disregard what has proven to be an effective means of protection from possible dangers or crimes.

The right to privacy is certainly valuable, but in China there are things that need to be more urgently protected, for instance, the right to enjoy a safe life.
