Who is Gan Xing in the movie "Red Cliff"? I don't think I've heard of it

Gan Ning, Gan Xingba, the first-class general of Soochow, regardless of appearance, commander, force, intelligence, are all first-class. If I remember correctly, Gan Ning also proposed to fight with Zhuge Lianglong. The strategic vision is almost the same, which shows that this person is a handsome man. He used to be a mountain king and a water thief. He decorated his big ship with stolen silks and satins, and was nicknamed the Jinfan Thief. If someone can be called a Jinfan thief, I think he is also a handsome guy. Now let's take a look at Gan Xing in "Red Cliff". He has a brutal look on his face. He feels like his parents have just been killed. He looks like he is going to fight anyone he sees. He is simply a barbarian and completely inconsistent with the image of Gan Ning in the Three Kingdoms. ! Think about it, everyone, how can such a handsome guy be played by a Japanese? Isn’t it a joke that Kodong has no talent? But John Woo may have considered the problems in the Japanese market, the requirements of investors, producers and others, and he should need a Japanese actor to enter the Japanese market. So John Woo deliberately found a Japanese actor who looked like his recently deceased father and mother to play a fictional general who seemed to have some connection with Gan Ning to break into the Japanese market. In this way, Gan Ning's image was not insulted, and the Japanese market was taken into consideration, killing two birds with one stone. You may say that Takeshi Kaneshiro is from Japan! Yes, he is of mixed Taiwanese and Japanese descent, but to be honest, I never thought he was Japanese. He has acted in many Hong Kong and Taiwan films. I think some directors in Hong Kong must not think of him as Japanese. Mathematically speaking, they are half Chinese and half Japanese. Speaking of Takeshi Kaneshiro, my first impression is that he is a very handsome Hong Kong and Taiwan star! Therefore, John Woo has good intentions, otherwise Gan Ning's change to Gan Xing would be completely redundant! I don’t know if anyone agrees with my point of view!
