I think you misunderstand what I am saying. Yangjiang was recognized as a city in the 80s.
"Yangjiang was permitted to become a city by the State Council of the People’s Republic of China in 1988 and is a prefecture-level city now."

Therefore to claim that "Yangjiang has a 1500 year history of knife making" makes no sense.
It is widely recognized the the
region had knifemakers the same as other areas of China.
I would start here:
The claim of 1400-1500 years came
after the fact and is now spread all over the internet
by Chinese knife companies and repeated by dealers.
Another way to dig into this is to try to identify names of famous past knife makers in Yangjiang
With places like Solingen and Seki you can literally go back hundreds of years.
Please understand, that I fully recognize Yangjiang as the world's largest knife/cutlery center in history. The size, automation, the scope of global market domination is unquestionable. But it is a designed-from-the-ground-up Chinese government project with a short history, unlike other centers with centuries of history and tradition.
From about 1970 onwards when costs in Germany rose, US Knife Importers turned to Seki Japan for OEM work. And that continued until the mid 2000s.
The Seki makers agreed to OEM contracts that allowed them to sell the knives in their domestic market but agreed to refrain from selling directly in the US market. China saw this as an error on Japan's part and started by doing all OEM work, and as soon as they were capable, entered the US market with their own brands. Which is of course what we have today.
The other issue is the enormous counterfeiting industry that the same Yangjiang factory complex contains. Which I suppose to a gfeat extent may be a side effect of having built such an enormous manufacturing capacity.
