In recent years, the Taipei City government has seized its takeover of the management of sewers as an opportunity to clean firebreak lanes between buildings that have been illegally occupied. The city has set up wooden frames for vine plants, planted flowering plants, and placed mosaics to turn back alleys into beautiful rear gardens.
近年來台北市政府藉著下水道接管的機會，逐步清除被市民違規佔用的「防火巷」，更進一步利用藤架、花卉植栽及馬賽克拼貼，進一步把後巷變成美麗的「後花園」。
