"Other countries" refers to nations outside of one's own, each with unique cultures, languages, and histories. They can vary greatly in size, population, and economic development. For example, countries like Japan and Brazil have distinct traditions and social norms that reflect their diverse backgrounds. Traveling to other countries can provide valuable experiences and insights into different ways of life. It allows individuals to learn about global issues, such as climate change and human rights, while also fostering international relationships. Understanding other countries promotes empathy and cooperation in an increasingly interconnected world.
