I received a short message about flying to Tie Bao for no reason. What happened? I didn't buy insurance at all!

This is just their advertising trick, you don't have to take it seriously.

Take a closer look at the text message, there should be additional conditions, such as manual confirmation to take effect.

If you believe that you can get insurance without spending money, others have to confirm it manually. If you find that you have been cheated, they will tell you that you need to pay the fee before it really takes effect. If it is not paid, it will not take effect. It's just a trick to fool you, or a fishing bait to lure you.

There will be no pie in the sky. Remember this sentence and keep your peace of mind.
