Red Propaganda Banners
Everywhere you guy in China, you see these red banners with white or yellow characters strewn all over the place. In neighborhoods, parks, over roads, on walls, in shopping centers…you get the point. These signs are truly ubiquitous. They serve many uses. Some of them are simply advertisements, like the one below advertising a film festival:

Zhengzhou Cinema Club Movie Festival
Of course, the more interesting red signs tend to be the ones that government agencies use to either diseminate information, stir up nationalist sentiment, or warn citizens against engaging in certain types of behavior. The name for these banners in Chinese is 宣传条幅 (xuānchuán tiáofú), or literally “propaganda banners”. However, it is important to note that the Chinese word for propaganda would more correctly translate as “dissemination” The Chinese translation does not necessarily carry the negative connotation of the English word “propaganda.” Following are some translated propaganda banners.
This was taken in an old Shanghai neighborhood, with some new, modern developments encroaching in the background

Create a civilized community; Build a beautiful homeland
This next one obviously refers to the earthquake that occurred last year near Sichuan.

Join forces to recover production; Work through the crisis to rebuild our homeland
This one is quite wordy, but the style of language is unmistakable

The rational use of land creates a resource saving-society; Protecting the farmland protects our lifeblood
Signs like these can often be often on walls around rural villages. It is common for signs to use compact blocks of four characters, which often translate into much longer English sentences

True dedication serves agriculture, the countryside, and the farmers
科学发展, or “scientific development”, is one of the key phrases that Hu Jintao often stresses in his speeches regarding development. It means developing China in a more environmentally friendly and technological way, basically.

Adhering to farmland boundaries and intensively saving the land protects and promotes the establishment of new mechanisms for "scientific development"

Enhance the awareness of environmental responsibility; raise the spirit of social ethics
If you find these interesting, please let me know, and I can try to translate some more again at a later date. My translations might not be perfect, so feel free to suggest a better translation.
Congratulations, you have completed one of the canonical blog entries for a stereotypical expat. For the next one, I suggest either a picture of a beggar, urban renewal zone (China is so dirty), or weird products at the grocery store.
I think I’ll go with the “stereotypical” foreigner who scoffs at every other White person that says hello to him (in ENGLISH, the nerve!) on the street
