Which is better, Hainan Refinery or Dongfang Petrochemical?

In fact, there is no strict sense of what is good or bad. The key is to look at which aspect. If you want to get a higher salary, CNOOC Oriental Petrochemical is the best choice, but you must endure loneliness and settle down to work for ten years before there is room for improvement. If you choose the upside, go to Sinopec Hainan Yangpu Refining and Chemical Company, because Sinopec recruits people according to the gradient, if the undergraduate course has a large upside; CNOOC only wants undergraduate courses and prestigious schools. Think about it, they are all dragons and tigers, and their leadership positions are limited. They can only last for ten or eight years.
