Recently, some netizens discovered that in the ticket purchase information of 12306, many trains had the word "pet" added next to them. The netizen asked: "What does this sign with the word 'pet' mean? Does it mean that pets are allowed on this train?"

In this regard, 12306 customer service said,The sign with the word "pet" refers to which train can handle pets.
The other party explained:"This sign should have just appeared recently. It didn't exist before. Because there were relatively few cars before, it might be troublesome for some passengers to check, so it was marked directly on the cars so that passengers can directly see which cars they can check in."
