This tool is sold in the exclusive garden shops in Denver and very fashionable to have, although I think not to cut weeds for pigs. Its use is for washing cars, parking lots, and different machinery, at restaurants for washing dishes, but never for gardening as we use it. To water garden plots and potted plants, the bucket and scoop is used. No suburban USA garden would be without hoses for watering, but then here in China, I have not seen a single grass lawn. If a tree survives it can be quite old.
Municipal parks seem to take up most of the efforts of gardening.
Gongshan Park is an example with substantial walkways. Sometimes a children play area is there and caged local wildlife for viewing. Always stairs lead up to a pagoda. At the entrance of the park many potted plants sit but as one wanders further the plants are in a more naturalized sitting. One interesting fact we discovered up river is that Gongshan Park was originally a forest saved to protect the town from mud and landslides.
