Extract: I think a lot of people will put Shanghai's unlucky date in 1966, or in 1953 of the Three-anti and Five-anti Campaigns, or perhaps the most sensible person will at least put the date in the time of Northern Expedition of anti-imperialism. However, these factors are considered externally. From the perspective of the Shanghai municipality and a possible Shanghai community, the real turning point was the deadly choice in 1869.
