Explanation:

 The Umbrella Movement is a pro-democracy political movement that was created spontaneously during the Hong Kong protests of 2014. Its name derives from the recognition of the umbrella as a symbol of defiance and resistance against the Hong Kong Police, and the united grass-roots objection to the decision of the Standing Committee of the National People's Congress (NPCSC) of 31 August.
The movement consists of individuals numbering in the tens of thousands who participated in the protests that began on 26 September 2014
