The city with the highest health insurance deficit in our country that cannot be investigated

A city of 1.3 million people has more oriental medicine hospitals than Seoul, a city of 10 million.
Oriental medicine hospitals are places patients visit for things like traffic accidents,
and long-term hospitalization is possible. If you investigate, you'll find plenty of malingerers.
The National Health Insurance Service knows this too,
but Gwangju has become such a "sacred ground" in Korea that they can't touch it.
The deficit from Chinese nationals is a problem, but the insurance deficit here in Gwangju is severe.
There is even a saying that people go to the hospital and lie down even if they just bump into a bicycle.
