Translation of the instructions for an anti-Japanese protest in China, from The Internet in China, Zixue Tai (original text here):
"Precautions
If you bring your own food and drink, don't choose Japanese brands;...
Cameras, video cameras, cell phones, tape recorders and other electronic products that are made in Japan should be avoided in order to prevent any unexpected accidents;...
Don't hurl hard objects such as rocks and metal ware. Instead, we suggest that you bring tomatoes, eggs, Koizumi's head portrait, a cigarette lighter, or Japanese national flags, etc...
Please cooperate with Uncle Cops, especially in front of the Japanese consulate - do not throw anything as Uncle Cop is looking at you, and throw an egg or tomato if he is not looking at you; however, if you throw an egg or tomato and Uncle Cop sees it, just smile at him.
When passing by Japanese-funded stores or companies, don't strike with the intention to damage, because if you do, the Japanese are going to ask our government for compensation. So act wisely.
Show caution when burning Japanese flag or Koizumi's head portrait so that you don't set you (sic) clothes ablaze and burn yourself."
