Can I only go to work in CNOOC through an intermediary?

Working in CNOOC is not just through an intermediary. CNOOC Shenzhen Branch is an oil company, which belongs to Party A and has no equipment. Many service companies provide technical services for Shenzhen branch there. Now if you want to enter, you can only enter through college entrance examination, at least with a master's degree. And because of the depression of the oil industry in recent years, you haven't hired anyone for several years. China Offshore Oil Corporation Sales Branch is a wholly-owned company of China Offshore Oil Corporation, which was established in April 2008. It is mainly responsible for the sales of refined oil and chemical products of China Offshore Oil Corporation.
