Introduction to Mihapo Boulevard: The construction of Mihapo Boulevard began in 1650. It starts from the Fountain of King Herne in the east, passes through two exquisite and lovely small fountains, and ends in the large fountain full of sculptures in the west. Although 500 meters is not too long, according to Leonardo da Vinci's aesthetic theory, the width of the street is exactly equal to the height of the two buildings. The avenue divides Aix in two. The streets in the south are straight and right angles, while the streets in the north are complicated with twists and turns. The "Two Brothers" cafe, located on the north side of the avenue, opened in 1792 and has a history of two hundred years. It has always been a gathering place for famous artists and literati.
