What window should I contact when breaking diplomatic relations in Huangdao District?

Pay social security and go to the administration hall.

Because the business of many administrative units is now concentrated in one service hall, the purpose is to avoid the staff running around in the non-stop department, and doing things in one hall can save a lot of time. Now there are government affairs halls everywhere. The government affairs hall integrates many administrative departments in the past into one office hall to handle affairs. The advantage of this is that it saves the time and efficiency of ordinary people, and it is not necessary to run many places as before. The government affairs hall includes traffic police, transportation, social security, industry and commerce, taxation and other administrative departments, so when you pay social security, go to the administrative hall.
