Tianwu Mountain is the meaning of the land that must be contested??

It's Tianwang Mountain, and it's a place to fight.

Isn't it "Tianwang Mountain"? The origin of "Mt. Tenno" comes from a famous war in Japan.

During Japan's Sengoku period, in August 1567, Nobunaga captured Inabayama Castle and the Saito family perished. Nobunaga renamed Inabayama Castle to Gifu Castle, which means "Zhou Wuwen King Fengming Qishan" in Chinese history. Nobunaga put forward the slogan of "the whole world is clothed" and wanted to march towards the reunification of Japan.

On June 2, 1582, Akechi Mitsuhide suddenly rebelled. The night before, Oda Nobunaga was watching chess in the Honnoji Temple, and the players played a three-calamity cycle, and the spectators were amazed. Oda Nobunaga was caught off guard and committed suicide at Honnoji Temple in Kyoto at the age of 49.

As his favorite ballad "Dunsheng" sings: "Fifty years in the world, compared with heaven and earth for a long time, but it is only a small thing, looking at the world, like a dream, once alive, how can there be no immortal..."”

Although the reasons for Akechi Mitsuhide's rebellion are different, Akechi Mitsuhide's dissatisfaction with Oda Nobunaga did not arise in a day.

On June 3, Hideyoshi heard of the incident and immediately and decisively negotiated peace with the Mori family. Soharu Shimizu, the lord of Takamatsu Castle, committed suicide by disembowelment in exchange for Hideyoshi's retirement (players who have played Mori Moto's Oath of the Three Arrows will remember this episode). In the early morning of June 5, Hideyoshi's army retreated lightning from Takamatsu Castle, and in the heavy rain of the Tsuna, they marched about 100 kilometers around the clock, and finally arrived at Himeji Castle, their home city, on the evening of the 7th.

This is the famous return of the Western University. Hideyoshi ordered all the funds and rations in the city to be distributed to the soldiers. In order to defeat Akechi Mitsuhide, Hashiba Hideyoshi is already desperate.

On the other hand, after the successful rebellion, Achichi Guangxiu was at a loss and lost time in vain. On June 13, the Battle of Yamazaki was held, with Hideyoshi's army of about 40,000 and Mitsuhide's army of 16,000, and the victory had already been announced. As a result, in the battle of Tianwang Mountain, Mitsuhide was defeated, and on the way to escape, he was attacked by peasants who wanted to receive a reward, and was killed.

At this time, Hideyoshi's rival Katsuya was far away in Echigo and the two armies of the Kamisaki family were unable to withdraw, and by the time Katsuya finally rushed back, the battle of revenge had already ended.

The above is the story of Tennoyama. To put it simply, the allusion to Mt. Tennoyama comes from the Warring States period of Japan, when Akechi Mitsuhide fought against Hideyoshi Hashiba after the change of Honnoji. Tianwang Mountain is a very important commanding height, and whoever can climb it first will win.

As a result, the monkey's army climbed Mt. Tenno, and Akechi Mitsuhide committed suicide in defeat.

Later, the Japanese Go community preferred to use this term to describe a crucial game in a decisive game of chess, or the commanding height of the appearance of both sides in a game of chess.
