City B is a famous ancient city. In the suburbs not far from it, there is a dilapidated and declining town called Guisi Town. It was later transformed into a distinctive tourist town by a couple who love ancient buildings. The characteristics of Guisi Town are not only the antique buildings, but also the furnishings of the houses and the clothes of the people, which are all imitated. Every visitor who enters Guisi Town has the feeling of stepping into the ancient world.
