1. Young people often prefer the city to the country due to various reasons such as better job opportunities, access to cultural events and entertainment, a vibrant social life, and a wider range of educational institutions.

2. Some young people may think it's easier to earn money in the city because there are more job opportunities, higher salaries, and better career prospects compared to rural areas. However, this perception may vary depending on individual circumstances and the specific industry or field they are pursuing.

3. Old people often like living in the country because of the peaceful and quiet environment, closer connection to nature, cleaner air, and a slower pace of life. They may also appreciate the sense of community and the opportunity to engage in activities such as gardening or farming.

4. The air in the country is generally considered to be cleaner and fresher compared to urban areas. The absence of heavy traffic, industrial pollution, and high population density contribute to better air quality in rural regions.

5. After stopping working in a city, old people may choose to move to retirement communities, smaller towns, or rural areas where they can enjoy a more relaxed lifestyle, closer proximity to nature, and potentially lower living costs. Some may also decide to move closer to their families or to places with better healthcare facilities. The specific choice will depend on individual preferences and circumstances.
