Gangzha district in Nantong city, East China's Jiangsu province, plans to build three new miniature street gardens in 2019. 

The three gardens are to be built at the same time as Bailongmiao River Gardens, which is expected to open during the first half of this year.

The district had built 23 such gardens by the end of 2018 and they will cover a total area of 52 hectares once the new ones are completed.
