What should I do/know when I arrive at the airport?

The subway (line 11) will take you directly to city centre, takes 25 minutes and cost 7 RMB.

Don't get a cab if the driver appraoches you, most of the time it will be "fake" taxi, and you'll end up paying 2 or 3 times the normal price.
A taxi fare to the city centre should cost around RMB 100 and will take about 40 minutes. Uber does not operates in China.

What's different from other countries/cities?

Everything happen on mobile apps (wechat) in China. You'll pay (almost) everything with Wechat.

Get your cash and VPN sorted in advance until you can set up a local SIM and pay on mobile apps
Try to setup a bank account when you arrive to get a Union Pay Debit card and link it to your wechat account

Google Translate and a good VPN (Astrill or ExpressVPN) will be your best friends

I need a SIM card

Short term: Go to any China Unicom store with your passport. They have a SIM card for 30 days and 20GB 300 mins for 99RMB. This SIM card will expire after 30 days.
Long term: China Unicom / China Mobile have many offer package for new numbers. Unlimited 4G (within the city) for about 99RMB/month with a yearly contract

Tips: Check if your oversea carrier (eg: Google Fi) include data roaming. You'll be able to bypass the internet restriction without VPN

Where should I stay/live

Nanshan (Hi tech park)
Futian

I need a bank account / debit card

You will need an apartment lease, passport (including resident permit), work permit and a local cell phone number to receive all the 2FA security text messages. If you have a tourist visa some banks might accept you, but some restriction has been implemented on tourists visa. ICBC or China Merchant Bank are great bank choices.

Tips: You can withdraw in almost every countries with UnionPay debit cards with really low fees (0.5%). With a limit of 100,000rmb/year and 10,000rmb/day

How to go from A to B?

Shenzhen metro and bus system are really convenient. Setup your wechat mini-app (ask a local) and you'll simply scan the QR code everytime you'll need to public transportation.
For iOS, Apple Maps works in China for all modes of transportation metro / bus in real time.
For Android, you'll have to download "amap" play.google.com/store/apps/details?id=com.autonavi.minimap . No english version but after few days of usage, you''ll get use to it.
Didi ( 滴滴出行 ) is the "Uber of China". Drivers will probably call you (in chinese) to confirm your location.

In Nanshan @ Hi-Tech Park:
The starbucks Reserve in HiTech Park has 2 nices big tables with power outlets. Go work there in the morning (afternoon is crowded)
