Loisir means leisure time. Les loisirs (used as a plural) are the hobbies or things you like to do in your spare time. The expression "à loisir" means "at will". By the way, leisure and loisir are sharing the same old french language origin.
The internet has greatly changed the way people use their leisure time. People now spend a lot of their leisure time reading articles online, watching movies and television shows, as well as communicating with friends, family, and work associates.
Leisure helped a lot of the people in Ancient China because it made people feel comfortable and more better because they were away from all the stress. It also helped the people because there were things to do during their leisure time that were entertaining.
