May I ask why there are five-color stars on the hat of warlord Feng in the TV series Jong? I remember seeing this kind of clothing worn by the Imperial Association Army before.

The five-color flag, also known as the harmonious flag of five ethnic groups, was the national flag of Beiyang government in the early Republic of China. The flag surface is red, yellow, blue, white and black in turn, with a ratio of 5:8. Red, yellow, blue, white and black represent the harmony of the five ethnic groups of Han, Manchu, Mongolian, Hui and Tibetan respectively, and the five colors chosen are the traditional favorite colors of the five ethnic groups. And these five colors are also the five colors represented by the five elements theory; It is also said that the five-color flag is taken from the five colors of the phoenix and also represents the five virtues of benevolence, righteousness, courtesy, wisdom and faith; Some people think that its five colors correspond to the traditional concept of five elements, and also cover the east, west, north and south in orientation.
