I think the happiness of an individual has little to do with income，the most important thing is how well they are connected with the family and friends.
Take my uncle and aunt’s life in the countryside for example, although they earn very little, they lead quite a happy life.
First of all, they are very diligent and good at gardening,so they plant lots of vegetables and raise livestocks, they always serve organic and authentic food for the family and friends.
In addition, they are very pleased with what they have, so they treasure everything in their life and bring out their best attitudes towards working and life.
Last but not least, they are very hospitable and treat their friends very well, especially my aunt, she is an excellent cook and famous for her cooking in our village, many people like her because she is so generous and selfless.
