Millai is a member of a local village, and she discovered that her village has undergone great changes recently. All these changes come from a product called Solar Media. At first there was only one family have it. Gradually, there were two, five, and nine families. In the end, you can see this product in almost all families in the village. In the shade of the tree, a group of people sat around Solar Media, staring at the screen. The topics discussed in the village have also begun to change, from children and housework to tips for maintaining health and hygiene, what the children have recently learned, etc.; children will argue about their favorite roles, share their feelings about movies, and so on. Millai also often participates in these topics. Among the many topics, the most people pay attention to agricultural techniques and hygiene knowledge. In the process of applying this knowledge to life, the crop yields in the village have increased, and the family’s food has become more abundant; at the same time, everyone is paying more attention to healthy drinking water and vaccinating children against infectious diseases. After Millai’s awareness of hygiene has improved, she will pay attention to changing some bad hygiene habits and promptly clean the breeding environment of diseases at home.
