During the Mongolian rule in China, China was extremely dark, and later Zoroastrianism in Persia was introduced to China. Zoroastrianism believes that darkness has passed and light is coming.
At that time, Mongolia came from the north and belonged to black, water and yin. China is in the south of Mongolia, which belongs to red, fire and yang. This coincides with Zoroastrianism, so Zoroastrianism played a great role in overthrowing Mongolian rule. At that time, the rebels against Mongolia were referred to as the Red Scarf Army.
Therefore, after China expelled the Mongols and established the Ming Dynasty, red became the auspicious color of China. In the Ming Dynasty, from official uniforms to people's wedding dresses, red was the benchmark tone.
Manchu is similar to Mongolia, coming from the north and advocating black and water. They are full of three waters, and their robes are all black, which is yin. Therefore, the zombies who were later interpreted by the people all wore Manchu official uniforms.
The whole period of Manchu ruling China was a period of struggle between the Han nationality and Manchu, which was characterized by the Han nationality being red and the Han nationality being bright. Manchu is black and gloomy.
After the Revolution of 1911, the national flag determined by Sun Yat-sen was a red flag all over the sky, and red accounted for 3/4 of the whole flag. Sun Yat-sen believes that red represents Han nationality, China and revolution. This is very similar to the Soviet red, so it is also advocated by the producers of * * *.
