Labor workers of Chinese exhibition companies certainly aren't contenders for an American spelling bee contest, but they should know the 26-letter modern Latin alphabet used in English, which constitutes the Chinese pinyin system, the very first lessons of 1st grade. Maybe workers mistook it for a language other than English, but the letter "l" in the word plastic is upside down.
Photo taken by Nina Ying SunI took the photo at the Chinaplas show, held April 17-20, 2008, in Shanghai. I jokingly told the company about the sign, and the manager said they didn't discover the error until the show opened, and since the sign was high up in the air, near the ceiling of the hall, it couldn't be easily fixed.
Plastics News had the same problem with our sign at last year's Chinaplas in Guangzhou. Our editor Bob Grace spotted the problem and had show service workers fix it right away.
Forget about the poor workers who make $100 a month, the question is if the exhibition company had any quality control or proof procedures. Or did they just skip it like some toy makers?
