I was given the history of the Chinese flag, by a friend the other day, here is the short version .... China's national flag was adopted in September, 1949. This flag was first flown in Tiananmen Square on October 1, 1949 - the day of the founding of the People's Republic of China.
The rectangular flag has a red field with five golden-yellow stars (each with five points) in the upper left corner. The star on the left is larger than the other four.
The red color of the flag symbolizes revolution. The large star symbolizes the Communist Party (which rules China) and the smaller stars represent the people of China. So there you go the Chinese flag !!
