Photos of trash polarized Chinese searching for proof to reinforce their prejudices or for material to illuminate the complexities of life.

On New Year's Day, China Daily posted four of photos on its microblog, showing how littered New York's Times Square was after its year-end celebration. The post attracted 3,000 comments and 14,000 retweets. Among the retweeters was People's Daily, which drew 9,000 comments and 17,000 retweets of its own.

China Daily's post was an oblique comment on the opinion that only Chinese show no respect for public sanitation. In a follow-up post, it added: "As the human flow for such fetes grows year by year, it becomes a common challenge for metropolises the world over for effective management of public spaces and its order and security while facing a sudden huge influx of visitors. We have paid a high price. But, in this age of global communication and traffic, it is ridiculous to discuss the issue in terms of racial quality."

The "high price" refers to the stampede in Shanghai on New Year's Eve in which 36 people died. "Racial quality" is a euphemism some critics assign to the inferiority of their compatriots when it comes to the less-than-desirable behavior in the public environment, such as littering, jostling and jumping the line.

It may not represent the mainstream voice of China, but there has always been an undercurrent of racism in China - against Chinese ourselves. Only in China would such a bad thing happen because Chinese are selfish, undereducated, scheming or too trustful, among other bad qualities, goes the argument.
