To be honest, Chinese products aren't necessarily the problem

Rather than Chinese products being the problem,
it is the strange mindset of the Chinese and the issue of Korean buyers aggressively slashing prices.
If you pay 500 won for a 1,000 won item,
the Chinese will make it a 500 won quality item and give it to you.
They don't say they can't make it.
When Korean buyers go to China to purchase goods,
they say, "Give me a discount because I'm buying in bulk,"
"The factory next door offered it for this much, so lower your price,"
"I'll keep ordering in the future, so give me a discount,"
or even, "Just make it cheap no matter what..."
Most buyers are like this.
I also used to deal with local factories in China,
and if you pay a reasonable and acceptable amount,
the products come out with quality comparable to Korea.
When ordering 100,000 units of a 1,000 won part,
saying, "Let's try to do it for 950 won..." is the right way.
If you try to buy a 1,000 won item by handing over 300 won,
it is actually stranger if the product comes out properly.
