As Ye Mo had said, Ye Yang and Ye Ling really did stay in the yard and didn't come over. They didn't even come over to ask about what was happening!
They only stopped what they were doing for a moment when they heard Liu Duo's voice, and then they continued with their work.
This was because, before Ye Mo had gone into the house, he told them, "Yang, Ling, Liu wants me to teach the wife how to read. As you guys know, she doesn't have a good temper, and she is especially fierce towards me, so she might fight with me and get angry. But since I'm the only one who knows how to read, I'm the only one who can teach her. If you guys hear anything later, you won't need to come in. Of course, I guarantee that I won't get mad and argue with her!"
And so, Yang and Ling brushed aside Liu Duo's screams. After all, she wanted to learn how to read, and only Mo could teach her!
