Let's not even talk about whether she can escape. Even if she really manages to get out, in this day and age, there are quite a few human traffickers outside. If she's not careful, she might get kidnapped and sold! Even if she can avoid the traffickers, Yun Shuangshuang can at most ensure her own survival. If she were to bring along Feng Jinyan, who's still erratic, they wouldn't even be able to leave this mountain village.
Although this village, due to its proximity to the town and the outside county, has residents who understand the law and don't engage in buying wives or similar practices, with a simple folk culture, still, if Lin Shuangshuang were to ask someone to take her and her erratic mother to the town, no one would dare to agree.
No one would agree to let a few-year-old child take her erratic mother and leave the village to make a living. It's practically a death wish. Doing so isn't an act of kindness but rather a sinful act.
