Which year did Alvin Cheng organize the rally with his schoolmates in support of the hong kong umbrella movement?
Umbrella Movement The Umbrella Movement () is a political movement that emerged during the Hong Kong democracy protests of 2014. Its name arose from the use of umbrellas as a tool for passive resistance to the Hong Kong Police during the occupation which was sparked by the decision of the Standing Committee of the National People's Congress (NPCSC) of 31 August of that year which prescribed a selective pre-screening of candidates for election of the region's leader.
2012 Kong Qingdong incident In January 2012, Peking University professor Kong Qingdong made televised remarks suggesting that many Hong Kong people were disloyal to China and still harboured a colonial mentality. Kong Qingdong called Hong Kong people "dogs" in response to an online video posted about a mainland Chinese child eating on the subway, which is prohibited by MTR regulations. This prompted a series of campaigns against Kong Qingdong in Hong Kong. About 150 people gathered at the Central Government's Liaison Office on 22 January to protest Kong's remarks.
