1. Look at the signboard: the real master Bao's cake is called "Master Bao's cake", not "Master Bao's cake". If there are words such as "Jin Dian" and "Jing", or there is an avatar, it is fake.

2. Look at the display screen in front of the door: the real master Bao shop has a display screen that shows the monitoring of the kitchen. If not, it may be fake.

3. Look at the shopping receipt: The real master Bao's receipt will have a long paragraph that says "We will never join" and a label of "original treasure".

4. Look at the number of stores: Master Bao has only 37 stores nationwide. If you see a shop with other addresses, it's not really Master Bao's pastry.

I hope the above information can help you identify the true and false Master Bao's shop.
