Try to divert your mother’s attention and attention.
She may want to buy these things now because she sees the value of collecting them or she has been brainwashed. If she is brainwashed, you can temporarily find a way to get her out of her current thinking, chat with her mother more, go out to play, buy things, go shopping, go to the mall, eat, divert her attention, and then think of ways to connect this with the emotional station. Delete it quietly. If it is in the Douyin live broadcast room, you can re-register your mother with a Douyin account so that she cannot see the relevant person's live broadcast for the time being.
