Where did the first five-star red flag in China rise?

The first five-star red flag was raised.

June 1 day, 1949, 10, is a permanent memorial day for the people of China. 1949 On this day, the blue sky and sunshine in Beijing were brilliant, and the ancient Tiananmen Square in the city center was completely new. Eight huge palace lanterns hung between scarlet columns, with eight bright red flags erected on both sides, and a huge slogan hung on the eaves: "founding ceremony, the people of China and the Central People's Government of China". On Tiananmen Square, there was a sea of people, red flags and a warm atmosphere of jubilation. People are waiting for the greatest moment in China's history.
