What was the experience of Beijing in ancient times?

It takes a lot of effort to get Juren to take the exam in Beijing. The biggest worry and trouble is getting sick during the trip. Beijing has a long way to catch the exam, full of unexpected difficulties and obstacles along the way. For example, when four or five people go together, they can take care of each other, learn from each other and eliminate loneliness. The imperial court and local officials also took good care of Juzi who took the exam. They either arrange bus transfers or give travel subsidies.
