Can the household registration office of qiaoxi district police station apply for a residence permit on Saturday and Sunday?

I can't. According to Article 7 of the Regulations on Working Hours of Employees in the State Council, state organs and institutions have uniform working hours and rest hours on Saturdays, Sundays and holidays, so the household registration office of qiaoxi district police station cannot apply for a residence permit on Saturdays and Sundays. 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. Holders of residence permits can enjoy the treatment of local residents.
