Why is the salary of Yongxin Optical so low?

The company's actual profitability and research and development capabilities are low. Yongxin Optical Co., Ltd. was established in 2005, formerly known as "Research Institute of Scientific Instruments of the Ministry of Education" founded by the Ministry of Education of the National Government on 1943 in Huanggewan, Shapingba, Chongqing. Its actual profitability and research and development ability are not so strong, and it does not need high-end management and technical personnel, and its salary is much lower. The company is mainly engaged in the research, development, production and sales of optical microscopes and precision optical components, and is a national single champion demonstration enterprise in manufacturing industry.
