What do you mean by "bloody battle"?

Do you mean "dragons fight in the wild, and their blood is mysterious yellow"?

This is a hexagram, which is explained as follows.

Day 6: The dragon is fighting in the wild, and its blood is mysterious yellow.

Solution: This is the sixth trick of Kun Gua. The dragon is yang, and this is yin, so the dragon war refers to the battle of yin and yang. Outside the city is the suburbs, and outside the suburbs is the wild. Huang Xuan refers to the colors of the sky and the earth respectively. Heaven and earth are the largest yin and yang, and their blood is mysterious and yellow, which means that the blood flowed from the battle of yin and yang, indicating that this is a fierce battle. When it comes to personnel, it means fighting from top to bottom, and as for casualties and bloodshed. In the late Three Kingdoms period, the story of Cao Taizu's war with Si Mazhao was exactly the same.

Story: Wei in the Three Kingdoms was founded by a generation of Yingjie Cao Cao, and it is the most powerful country in the Three Kingdoms. Who knows, Cao Zhi's descendants are all black sheep, and later Wei Yan became the eldest son of Sima's family. By the time Cao Fang came to power, Sima Shi had actually mastered the power. Sima Shi is a man with a sword, and all political affairs are decided by him, regardless of Cao Fang. Cao Fang was angry, however, and Miuma killed Sima Shi. Who knows, things were not kept secret, but Sima Shi abolished his throne. Sima Shi had no time to usurp the throne, so he had to establish Cao Taizu as the new king. Wei Wendi's grandson, Cao Mao, was originally awarded the title of noble duke, but now he is an emperor, and he wants to do something. That's right. Sima controls the whole state affairs. After Sima Shi's death, Si Mazhao claimed to be the commander-in-chief of all military forces in the world, grabbing aristocratic rural people everywhere, and his ambition to usurp power became increasingly obvious. Everyone knew that the idiom "Everyone knows Si Mazhao's heart" came from here.

Seeing Si Mazhao's arrogance, Cao Mao hated it in his heart, but he was afraid of Si Mazhao's power, so he had to write a poem "Hidden Dragon Poetry" to vent his dissatisfaction. The poem says: if the dragon is trapped, it can't jump into the abyss. If you don't fly into the sky, you can't see the fields. Sowing at the bottom of the well, loach and eel dance at the bottom of the well. An official named Jia Chong knew about it and immediately reported it to Si Mazhao. Hearing this, Si Mazhao compared him to a fish and an eel in his poem. He was very angry and immediately went straight into the palace with his sword. In front of all the ministers, he sharply reprimanded Cao Mao and publicly threatened: "Do you want to be the second Cao Fang of Cao Mao?" Cao Mao returned to the harem and cried for a day. Finally determined to eradicate Si Mazhao. He called three ministers, Jing Wong, Wang Shen and Wang Ye, to discuss the matter. Jing Wong suggested that he learn the lesson that Lu Crusade family failed and was exiled. However, Cao Taizu said that he would rather die than let Si Mazhao go wild. So Cao Taizu called 300 soldiers to kill Si Mazhao, but Jing Wong didn't listen, while Wang Shen and Wang Ye took refuge in Si Mazhao and became traitors. Before Si Mazhao could start work, Cao Mao was killed by Si Mazhao people, Jing Wang and three hundred soldiers were also killed, and the city was bleeding.

Revelation of life: The six hexagrams on Kun Gua are extremely yin things, and extremely yin things force Yang to fight against them, just like dragons fighting in the wild. As a man and a minister, Sima's power overthrew the world, bullied the master of Wei, and a war broke out. As a result, Sima Yi usurped the country, and Wei's master died and lost his country. This moral and story tells the world that when the strength of the two sides of the contradiction is very different, the weaker side must not act easily to prevent throwing stones and asking for directions, but should wait and create opportunities and judge the situation before acting.
