Cross-culturalism is when people from different cultures and backgrounds come together and share their different experiences, beliefs, and cultures. Cross-culturalism can happen in different places when different groups of people interact with each other. For example, when people from different countries move to a new country and interact with their new neighbors, they might learn about how the residents of their new country live and think differently compared to their own culture. This means that they both learn new things about each other and become more open-minded and understanding of different cultures. At the end of the day, when people interact with different cultures, it can make them appreciate diversity more and make the world a better place for everyone.
