As far as I know, the prototype of Tiger Brother in Pleasant Goat and Big Big Wolf is not boxer Tai Sen. Pleasant Goat and Big Big Big Wolf is an animated film from Chinese mainland, produced by China Orange Sky Jiahe Film and Television Culture Co., Ltd., and the prototype of Tiger Brother comes from the traditional tiger image in China.

In this animation, the tiger is a tiger in a flowered shirt. He usually tries to catch sheep like Pleasant Goat by improper means, but he is always stopped by just people like the Wolf. Tiger's vivid image and personality have become one of the most popular characters in this cartoon.

Therefore, it can be concluded that the prototype of HuHuHu is not Tai Sen, but the traditional tiger image of China.
