Bai Hua sends me text messages at midnight every day.

See if you have opened ant flowers in Alipay. If you have opened it without knowing it, sometimes you don't know it, he will prompt you. Another possibility is that someone owed you a fee for your phone number before and has not paid it back yet, so send a text message to remind you to repay it. In this case, you should contact the customer service in Bai Hua to explain the situation and let them handle it. Don't send text messages to harass.
