The Significance of July 1 Day's Party Building Day

As a great political party, China's exact birthday was not verified by party history workers until the late 1970s. 1938 in may, the central leadership first proposed the party's birthday, which was based on the memories of Chairman Mao and Dong, two comrades who had attended a university in Yan 'an at that time.

They only remember that one summer, the weather was very hot, probably in July. Because it can't be verified accurately, July of 1 year is set as the birthday of the party concerned-a day that looks more casual than casual.
