Editor's note: Amity between the people holds the key to sound state-to-state relations. China Daily will come out with a series of stories highlighting Chinese cities' special connections with sister cities, mutual understanding, trust and friendship between peoples of different countries and cultural backgrounds, and shining light on "city diplomacy".

Shanghai native Shi Yue, a junior art director at McCann Worldgroup Italy who has been living in Milan for 10 years, is always amazed by the similarities shared between her hometown and the Italian city.

Open, inclusive, developed, international, and trendy are the words she used to describe the two cities, both serving as global hubs for many industries, in particular, fashion and design.

"The two cities are alike," Shi exclaimed.
