When an alien enters China Customs, the immigration permit sticker attached to the passport is called a visa. After entering China, he is registered in the local registration office of the local area and submits a passport visa. This is called the residence registration of foreigners. It is the confusion.
Renting a house, I don't know the current foreigner management regulations in Beijing, but after renting a house, I have to bring a rental contract (the landlord's relevant information certificate is also estimated to be carried). I immediately went to the local police station to register and report that it is 100%.
