Which is better, Dalian Huaneng Power Plant or Dalian No.7 Petroleum Plant?

My father is in oil, although he is well paid, but after all, he is just a factory, paying wages on a monthly basis, giving bonuses in big sections and so on.

Another relative is driving in Huaneng, and his evaluation of Huaneng is: "You don't have to tell you what it is, you can send money at any time, just take it (I suspect their leader is money laundering)" Anyway, as long as you can enter Huaneng for one year, it will be no less than 7W.
