A glacial valley cross-sectional shape is a U shape whereas a stream valley is usually a V shape. The U shape comes from the scouring action of the alpine glaciers which carries rocks with it which can abrade the walls of the valley and the glacier occupies the whole valley so scours out such a shape whereas the stream cuts down and water washes in from the sides of the valley into the stream or river creating the V shape.
In April 1927 Guomindang forces, aided by urban gangsters and warlord militia, attacked members of the Chinese Communist Party (CCP) in Shanghai. Hundreds of communists were rounded up, arrested and tortured; most were executed or assassinated. The Shanghai Massacre, or ‘April 12th Incident’ as it is sometimes called, was a pivotal moment in the Chinese Revolution. It triggered a nationwide purge of communists from the Guomindang and several years of anti-communist violence, dubbed the ‘White Terror’. Surviving communists were either forced underground or into rural and provincial areas outside Guomindang control. The events of April 1927 marked the end of the First United Front between the CCP and Guomindang and the end of Soviet Russian support for the Nationalists. The CCP leadership was forced to reassess its revolutionary strategy in the wake of the events in Shanghai.
