Chinese heavy "dtuy" wrench

"Many of the students and teachers at our schools spell worse than this, and their first language is English. Of course that only applies to the students that can actually read and write by the time they leave High School. I am willing to bet that there will be very few students in China that have that problem."

Absolutely right on.

"All that aside, I love these mistakes in signage and language interpretation. One of the funniest that I recall was on a builders van in Singapore that said "Amateur Construction Company"."

The sign is absolutely correct. "Amateur" in its original and strongest meaning still means "lover of (whatever)", from the Latin 'to love'. For example, amateur astronomers make important contributions to astronomy every day - using their equipment, and at their own time and expense. You may be aware that Galileo, Kepler, and countless others were all amateur astronomers" until their genius gave them patrons (today's "sponsors") which made them "professional". Unfortunately (and mainly in North America, I think) the word "professional" has become to mean "I/we get paid for our work" such as it may be, regardless of the work's quality.
I think "Amateur Construction Company" is a great sign, as unconventional as it sounds. How many of us can write a logo in Chinese that cannot be made fun of?
Still, I see the humour in this ad.
