Can social security for residents in Anyang Longan District be used in Yindu District?

Of course. Can be used in the same district, not across the city. Residents' medical insurance is only used in this city and managed according to the territory. The funds on the medical insurance card are divided according to the payment of the insured person in the urban area. The insured's medical treatment and drug purchase are settled by cities and counties, and residents' medical insurance cannot be used across cities. You can only see a doctor and buy medicine in its designated hospitals and pharmacies. So it can't be used across the city.
