452 years ago today, on May 13, 1573 (April 13, 1573, the 1573 lunar calendar), the famous Japanese general Nobusuki Takeda passed away. Takeda Nobuhiro was born on November 3, the first year of Dayaga (December 1, 1521), and died on April 12, the fourth year of Yuangui (May 13, 1573). He was a great food doctor (from the fourth position), Shino, Kafi Guardian, and the 17th generation of the family governor of Takeda in Kafi. His original name was Haruobu Takeda, and Shinzo was his legal name. Tarō Nakata is the eldest son of Nobu Takeda after Saburo Yoshihiro, a famous Genji family. A famous general in Japan during the Warring States period. Because of Ren Jiafei's protection and outstanding military ability, he was called "Tiger of Jiafei" and "Dragon of Yue Hou" Shangshan Qianxin could be said to be a moment of excellence. On April 12, 1573, Nobugen Takeda died in Komaba, Shinano, at the age of 53. According to the letter Xuan's last words, three years secret not to send funeral, and by the letter Xuan's brother letter Lian served as a shadow warrior. In the fourth year of Tianzheng, Xin Xuan's body was officially buried in Huilin Temple. Xin Xuan failed to complete the great cause of reunification, and his life's efforts and dreams finally came to naught. It is said that when he learned of Nobin's death, Uesugi Kenshin cried for three days and said that he had lost his lifelong opponent and was determined not to fight with Kapi again. Only two years after Takeda's death, his son Takeda Katsuyoshi was defeated by the Tokugawa Oda Allied Forces in the Nagashino War, and the Takeda family fell into decline. In 1582, under the attack of Oda and Tokugawa, Takeda Katsuyoshi and his son Takeda Nobusuki committed suicide on Mount Tianmu, and the Takeda family was destroyed. Takeda Shinhiro expanded his territory from the Kapi state to the Enjiang state, Shinnon state, Kapi state, Izu state, Surukha state, Mino state, Hita state, Ueno state, Sangmo state, and part of Sanhe state. Moreover, the surrounding opponents are not weak, which shows his extraordinary military and political talents. Takeda Nobuhiro's military strategy and political approach left an influential mark in the history of Japan's Warring States. The military flag of "Wind Forest and Volcano"(as fast as the wind, as Xu as a forest, as invading as fire, and as immovable as a mountain)(also known as Sun Tzu's Four Flag of Truth) was used in the words of "Sun Tzu's Art of War" and was extremely powerful for a time. Xin Xuan was particularly good at commanding the elite cavalry of Jiazhou in terms of use and achieved victory with flexible and witty tactics. Created the "Jiazhou Stream" art of war. Takeda Shinxuan is famous for his outstanding military command, but he is different from ordinary militaristic generals. Shinxuan is also an outstanding civil administrator. In the 16th year of astronomy (1547), Shinxuan formulated Article 55 of the "Jiazhou Law Order" commonly known as "Shinxuan Family Law", which stipulates in detail the relationship between the monarch and his vassals and the rules that his vassals should abide by. He is one of the famous representatives of the national laws of the Warring States Period; It was devoted to the governance of the territory, especially the water control works built on the Buwu River and Dichui River in Jiafi for half of its life. It used the most advanced weir and diversion technology. It was the largest and most famous embankment in the Warring States Period. Its benefits and future generations, it was called "Xinxuan Dike" by later generations and still plays a role today. Shinxuan is also known for his ability to cultivate talents. His famous "Four Takeda Ministers","Twenty-Four Generals", and Sandanzheng gathered into the most excellent and loyal and stable vassal group in the Warring States Period. Published in the Edo period, the art of war in Kaizhou became a legend, and Shinxuan was recognized as the first art of war in the Warring States. Xin Xuan believes in Buddhism, and he is the chief monk of Tiantai Sect. Religious belief is an important part of governing the country with faith and metaphysics. Yuan Huyin, the famous general of the Takeda family, once left due to his belief (Huyin believed in the Nirhiren Sect). Shinxuan's religious policy also reflects the unique reality of the Warring States Daimyo. For example, allowing monks to pay a certain amount of service money to marry a wife was obviously more reasonable than forcibly prohibiting the phenomenon of monks marrying wives, which was almost openly prevalent at that time.
