"Rivedroite" originally refers to the left bank of the Seine River in Paris, France. It is a cultural shrine with cafes, bookstores, galleries, art galleries and museums, and is the territory of intellectuals. If Paris is a beautiful woman with a variety of amorous feelings, then the "left bank" is like the face of Paris, which needs to be carefully decorated every day.
The word "left bank" can be applied to many places for two reasons: 1, and "left bank" is like a fashionable label, and many people expect this word to turn the stone into gold. 2. For those who don't know the real "left bank", this word has a little elegant and leisurely taste of petty bourgeoisie.
