Lausanne is surrounded by mountains and lakes, and the city can be divided into two areas: the lake is a leisurely, modern, and tasteful temperament; the old city on the mountainside is a nostalgic, ancient building, which exudes the charm of historical connotation. The city is beautiful, many famous European literary artists such as Byron, Rousseau, Hugo and Dickens have lived here, so Lausanne has the "international cultural city".
