China is so big, which city your coworker worked in ? Different parts of China had different "standand". Poorer area had many "invention" For example:
1)Colour of wire is not important. L,N,E-SAME colour.
2)Use the cheapest wire- Al wire
These so called "sparkies" learned the above "skills " in their hometown.
When they rushed to big cities, they can't compete with liscensed local sparkies's quality work, only way to "survive" in the market is lower their wage.
"You got what you paid for" always apply to everything in China, from goods to services NOTHING had expection. "Pay more" got "better quality".
