May I ask: Who are Toyotomi Hideyoshi, Nobunaga Oda and Tokugawa Ieyasu? What historical figures are equivalent to China?

They are all big bosses. The leader of Japan during the Warring States Period.

Nobunaga, equivalent to Cao Cao, was suddenly wiped out by traitors when he was close to reunification. For example, Emperor Xian of Han successfully wrote a letter with clothes, and was defeated by (General Oda, barely equivalent to Marten or Dong Cheng).

Toyotomi Hideyoshi is almost Sima Yi, who has made great contributions to the unification of weaving fields. When the boss dies, he immediately defeats his opponent, nominally rules the country and plays the trick of supporting small business owners.

Tokugawa is equivalent to nominally surrendering Sun Quan of Cao Cao and Cao Pi, so is Tokugawa, and both of them live longer. But the difference is that Sun Quan has no chance to unify the whole country, while Tokugawa has.

This is equivalent to the early death of Cao Cao, the reunification of Sima Yi after he came to power, and the pretence of surrendering their Sun Quan. After Sima Yi's death, he destroyed their descendants and took the lead in unifying the whole country.
