About renewing/applying for a residence permit, I was scouting and found this info from somewhere however it might be outdated- This is for Shanghai. Is this relevant today?
Documents You Will Need:
Completed Foreigner Visa and Residence Permit Application Form (obtainable at the Exit-Entry Bureau itself), with passport photo
Original Registration Form of Temporary Residence from your district’s police station (

)
Copies of your current employer’s valid Business License (

?), Organization Code Certificate (


?), and Certificate of Approval (

?) for foreign-invested enterprises
Application letter from current company (

?), with company stamp
Your newly collected Alien Employment Permit (typically valid for one year), and the Employment Registration Form (1 copy will be returned to you when you collect your Alien Employment Permit if you applied for a new one. If not, ignore this.)
Your passport
Not really a document, but you’d need some money to have your passport couriered to you. Typically 25RMB.
Application Procedure:
Head to the Exit-Entry Bureau at


?1500? (1500 Minsheng Road, Pudong New District), from 9:00-17:00 Monday-Saturday, walkable distance from the Shanghai Science & Technology Station (Metro Line 2) with your application material. The foreigners’ application is on the 3rd floor.
After getting a queue number, proceed to fill out the Foreigner Visa and Residence Permit Application Form while waiting
If you plan on having your passport couriered to you with the residence permit, purchase an envelope from the counter behind the form-filling counters. This envelope has a courier form where you fill out your address.
When it’s your turn, hand over your application documents and the envelope. You’ll be given a white slip with the date that your passport will be ready, either for you to collect from the Bureau or delivered to your address. It typically takes 5 working days. The amount you have to pay upon collection will also be stated on the white slip. For residence permits of less than a year, it’s 400RMB. Your residence permit validity will be exactly the same as the validity of your Alien Employment Permit.
On the date of collection, if you’re collecting your passport at the Exit-Entry Bureau itself, be sure to bring the white slip and pay at the payment counter on the 1st floor (turn right after entering the main door). If you arranged for the courier to deliver it to your doorstep, be sure to have your cash ready.
