Why can my daughter-in-law receive text messages? How can I delete them?

Your spouse can receive text messages when you book a high-speed rail ticket. Maybe you filled in the wrong mobile phone number when you registered, or the mobile phone number you used is your spouse's. I suggest you check whether the mobile phone number is filled in correctly first. You can change your mobile phone number if you have any questions. If there is no problem, you can also call customer service to cancel.
