Why do Japanese samurai express their loyalty by cutting their bellies?

Only Japanese samurai are qualified to perform abdominal incision, which is a bushido spirit. Bushido spirit is the spiritual pursuit of Japanese samurai class in feudal society. Bushido spirit advocates loyalty, faith, honesty, martial arts and reputation. Then why did the Japanese samurai cut their bellies to show their loyalty? Why not choose another road?

Japanese countries mainly eat rice. They think that rice has a soul, and the rice people eat is digested and absorbed in the abdominal cavity, so the place where the human body absorbs and purifies the soul is the abdominal cavity, so the human soul lives in the abdominal cavity. The samurai disembowelled to release their souls. We watched the TV series of the Anti-Japanese War. After the Japanese generals were captured, they all chose caesarean section. We in China generally believe that suicide is a sign of cowardice and irresponsibility. Then, in the spirit of Japanese Bushido, caesarean section is just a way to make amends for not completing the task. At that time, Japanese soldiers were all loyal to the emperor and did not complete the task of war. They won't choose to be prisoners. Caesarean section is a way for them to express their loyalty and determination to the emperor.

? In fact, it is impossible for people to die quickly through laparotomy. There are many nerves in the human abdomen. Once cut, it is very painful and the average person can't bear it. And the real abdominal incision is to cross the knife on the stomach, first cut it horizontally, and then cut it vertically. The whole process is to endure severe pain. When Japanese samurai learn the spirit of Bushido, they will practice abdominal incision. If you don't die during abdominal incision, someone will cut your neck, and this knife can't be cut off. Keep your head and neck together until you die. The whole process of caesarean section is very cruel and painful, which is difficult for ordinary people to complete. In Japan, ordinary people are not qualified for caesarean section, and then samurai are qualified and qualified to complete it, conveying a bushido spirit, that is, even if they die, they must die with dignity.
