It's hard to get in. Dalian Salt Chemical Group Co., Ltd., formerly known as Dalian Fuzhou Bay Salt Factory, was founded in 1848 and has a history of 170 years. It is a large enterprise with strict recruitment conditions and good salary, so it is difficult to enter the fifth factory of Dalian Salt Chemical Group. Dalian, also known as the romantic city, is a prefecture-level city, a sub-provincial city, a city with separate plans, a megacity under the jurisdiction of Liaoning Province, and an important central city along the northern coast of China as determined by the State Council.
