Since the Olympics in Beijing 2008 bring in a lot of work, the Beijing government decided to to improve this as well and started up a special program. THis is called the "Use Accurate English to Welcome the Olympics Public Bilingual Sign Standardization Drive."
As part of this program people can send in their observations which then will be taken care off. A few quotes from the website:
"Residents sent in a wide range of complaints," said Zhou Chen, an official at the programme's office.
For example, the "Racist Park" sign was spotted and posted online by a Canadian student named Eric.
"It suggests China hates other nationalities; and foreigners coming to China would feel uncomfortable," he said, adding: "I love China, please change it."
Jay Shen, from the United States, pointed out that the introduction to the Summer Palace says "three quarters are under water" instead of "three-quarters of the park is a water surface."
The website where people can report their findings is: http://www.bjenglish.com.cn
