Why is COFCO Xinsha (Dongguan) a subsidiary of COFCO, but its attribute is foreign capital? Please give me your advice ... what is the salary of the fresh graduates of COFCO Xinsha?

In the past, COFCO Xinsha (Dongguan) was a joint venture named Dongguan Zhonggu Oil&Fat Co., Ltd., which was jointly invested and operated by Zhonggu Grain & Oil Group Co., Ltd. and (Hong Kong) Jiaxin Industrial Co., Ltd., of which Zhonggu Grain & Oil Group Co., Ltd. held 75% of the shares and was an absolute holding company. Later, Zhonggu Grain and Oil Group Co., Ltd. was merged by COFCO. I'm not from COFCO, but opposite COFCO. I heard that the treatment is quite good. It's just that the environment here is a little bad and the coal dust is too big.
