Tibet has been a part of China since 1950. This means that China controls Tibet, deciding who gets to live there, what the people in Tibet can do, and how the land is used. They have their own government and laws, which are different than in other parts of China, but they still have to follow all of China's laws. China has built lots of roads and railways in Tibet, which has allowed people to travel and goods to be traded more easily. They have also built schools, hospitals and other useful buildings. However, some people in Tibet do not feel like they are in control of their own lives and some have protested against Chinese rule, so it can be a complicated situation.
