Where can I apply for the certificate of long-term residence in Songjiang Zhang Ze? help

Just go to the social security center. You can ask or look at Baidu map. Now there is no long-term residence permit. Now all those with social security apply for one year. Don't pay off your social security. Just go to the social security center or community service center with your residence permit every year, and you don't need to apply for it again (it seems that there is no such thing as Zhang Ze).
