Asking about social security in Zhuhai

I understand that social security is applicable to enterprises affiliated to cities and counties and their employees and retirees within the administrative area of this Municipality, and enterprises withhold and remit relatives, saying that enterprises in Zhuhai can pay medical insurance accounts for sick people, towns choose basic medical insurance for urban residents, and rural accounts choose new rural cooperative medical care. The coordination of the two types of insurance was actively promoted. Insured residents implemented a two-way referral system with fixed-point first diagnosis. Community health services, specialized hospitals, hospitals and stores cooperated with secondary and lower medical institutions to determine the first-visit medical institutions, and tertiary comprehensive referral medical institutions determined the fixed-point referral medical institutions. Insured residents' doctors should first specify the first-visit medical institutions to diagnose their illness. If referral is really necessary, they should be transferred to the hospital for treatment. The first-time medical institution will be transferred to the designated referral hospital for hospitalization with the transfer certificate. If the condition is stable, it is necessary to transfer to the designated first-visit hospital (in other words, the disease must be treated in a designated community service hospital or a designated hospital, and the hospital can prove that it can be transferred to another hospital for treatment, etc. The proportion of urban residents' basic medical insurance fund payment is 75%, 60% and 50% respectively according to the proportion of secondary and tertiary medical institutions determined by medical institutions at the same level (including community health service institutions). Urban residents' continuous insurance contributions will be increased by 80%, 65% and 55% respectively (in other words, they will report more frequently if they are hospitalized), and each high payment limit can be reported as 20,000, and the payment period is limited to 2-5%.
