There are shops and flower stalls selling all kinds of flowers on many streets in the city. Residents generally like to plant, buy and give flowers to each other. Walking in the city, you can smell the fragrance of flowers almost everywhere. The whole city is like a blooming flower. With the white or light yellow houses, Sofia looks particularly beautiful and elegant.
