"你可以在社区环境中做普遍主题，但不能在普遍环境中做社区主题。"

Simplified Meaning:

When you talk about big, universal ideas like love, friendship, or bravery, you can show these ideas through the everyday lives of a small group of people in a village or neighborhood. People can understand these big feelings and experiences no matter where they come from because they are common to everyone. For example, a story about a small town football team overcoming challenges can show themes of teamwork and determination that anyone can relate to, regardless of where they live. However, if you try to focus only on the very specific details of that small community, like their local customs or inside jokes, it becomes harder for people from different places to connect. They might not understand or care about those small, particular things because they are not part of their experience. So, if you keep the focus on the big, common themes, people from all over the world can find something in the story that speaks to them. When sharing your own stories or experiences, remember to highlight the universal feelings and lessons that others can relate to, no matter where they are from.
