This was because after Jing Qian released the post, her parents had called her and were screaming at her. Not only did they scream at her, they even told her that she would have to repay the debts on her own.
After ending the call, Miao Lanqi cried, and after seeing what Mother Qin said, she could no longer think rationally. She immediately posted the recording of her phone call with Jing Lu.
[Falling Petals (v): Defamation? Your little sister was the one who called and told me all these. Thank god I have a recording of it. Otherwise, with your fans and your 'boss', I would never be able to prove myself!]
Everyone turned up the volume, and the recording was of the phone call between Jing Lu and Miao Lanqi.
