Sorry for no offering a direct translation in Chinese, but if this can help :
L'Homme de Rosella Fiora is a perfume by Rosella Fiora for men.
"L'Homme" is the title of the perfume and means "Man" (or "The Man"). I guess this name is meant to show that the product is intended for the virility of "the man" that will use it.
"Rosella Fiora" is the brand (or name used to spread the authenticity of this perfume through a well-known name).
"Paris" is...well...it's a thing for luxury products like perfumes to name the city where it (would) come from. So Paris is for the French city : Paris.
Hope I could help...
In Chinese, i guess "hommes" are "男人 " ?
