Why did Tangshan produce so many rich people?

Since the reform and opening up, Tangshan city is indeed rich in resources. A few people get rich overnight, and 80% of people in Tangshan hold 1% of the wealth.

It is true that Tangshan and Qian 'an have iron mines, while Kailuan, Kaiping and Fengnan have abundant coal mines. The oil reserves in Fengnan Nanpu area are about 654.38 billion tons. There are ways to make money in other areas. Especially in Fengnan area, small steel mills and ironworks have mushroomed in recent years, and the secondary industry of steel processing has done well. Therefore, Mercedes-Benz, BMW and Porsche, the owners of steel mills, run as many as taxis on the road.

As for whether there are 6 billion tons of iron ore resources, this is only hearsay and has not been really verified.
