Can I apply for a residence permit with the sales contract and ID card of the landlord and the relocated household?

Of course. According to the inquiry and news network, you need to provide a house sales contract and a landlord's ID card to apply for a residence permit. Residence permit is an attempt made by some developed cities in China to learn from the "green card" system of developed countries, which has accumulated experience for China to formulate skilled migration measures and eventually form the national "green card" system of China.
