Hong Kong's rich vernacular culture is the subject of many works by Michael Wolf. In his new book 'Hong Kong umbrella' he turns his attention to countless umbrellas in the back alleys of the metropolis. Stretched and in all colors and patterns they lie, stand or hang everywhere, protect laundry, goods, market stalls and bikes or someone lies down underneath to have a snooze. This is the fourth of 9 volumes, Michael Wolf's 'Encyclopedia of street life in Hong Kong's Back Alleys'.
