1. About 2 hours before the flight takes off, you can pay attention to the flight information screen or ask the airport staff, and they will update the boarding gate information in time.
2. If you pass the security check, you can check the flight display screen in the waiting room, which will show the boarding gate information of each flight.
If you haven't passed the security check, you can apply for a new boarding pass at the check-in counter, which should have the correct boarding gate information.
The airport in every place is different. Large ports and airports like Shanghai and Beijing are very big. You have to see clearly what your terminal is (it will be written clearly when the ticket is issued). If you take a taxi, you need to tell the driver what the terminal is, otherwise you will have to take many detours. After arriving at the terminal, find the airline counter.
For domestic flights, just show your ID card, then check your luggage and get your boarding pass. The boarding pass will clearly indicate which boarding gate you are, and wait at the boarding gate. At that time, the staff will tell you (or the electronic screen will show) when and where the flight can board, and you can board with your boarding pass.
To sum up, if there is no boarding gate information on your ticket, don't worry too much, just pay close attention to the flight information and airport announcement and follow the relevant guidelines to go to the boarding gate.
