What is the difference between employer liability insurance and social security that employers are obliged to pay for workers?

Employer's liability insurance is commercial insurance, which bears the following responsibilities: during the insurance period, any employee employed by the insured suffers from an accident in business or an occupational disease prescribed by the state, resulting in disability or death, and the insurer shall be responsible for the economic compensation liability that the insured should bear according to the laws of People's Republic of China (PRC) (China) (excluding the laws of Hong Kong, Macao and Taiwan). Social security is social insurance, which generally refers to "five insurances", including endowment insurance, medical insurance, unemployment insurance, work injury insurance and maternity insurance; Among them, old-age insurance, medical insurance and unemployment insurance are premiums paid jointly by enterprises and individuals, while industrial injury insurance and maternity insurance are entirely borne by enterprises. Individuals do not need to pay fees.
