How about Ningbo Zhenhai Refinery and Shanghai Boiler? If it is a key undergraduate graduation?

Of course, Ningbo Zhenhai Refinery is better, Sinopec is the largest enterprise, with a processing capacity of 23 million tons, and monopoly enterprises are more secure. Because of the good treatment and geographical location, employees basically did not jump ship (several jumped ship to CNOOC Huizhou for refining). A few years ago, Sinopec's refining sector suffered huge losses, and Zhenhai Refining and Chemical Class took photos to get money, with many year-end awards. The main business object of boiler plant is the oil refining industry, and the market competition is fierce. If the refinery really goes bankrupt, the boiler plant will be finished.
