For a local SIM, go to an official China Mobile/Unicom/Telecom store with your passport.
Ask the staff to activate data and confirm the balance before you leave the counter.
Top up via the carrier app or a convenience store.

Mistakes that cost money or time

Buying a local SIM on day one and losing WhatsApp for the whole trip.

Questions people actually ask
