In the old urban areas of Beijing, China, with the changes of the times and urban planning, the original appearance has gradually changed - the originally narrow streets are slowly filled with cars, and familiar neighbors have moved outside the city. Hutongs, as the soul and symbol of this ancient city, are also quietly changing.

There is a group of young people from various industries, including architects, designers, pastry chefs, musicians, coffee shop owners, painters, craftsmen, and so on. They have gathered together and chosen to be active in the hutongs of old Beijing in a new way, forming a new ecology of hutongs and bringing new hope to the hutongs.
