Why do many people denigrate Professor Liu Feng?

Liu Feng used physics to explain Taoism, Zen and Buddhism, and concocted a so-called high-dimensional wisdom theory, just like Zhu Qingshi used quantum mechanics to explain Buddhist scriptures, which puzzled many people.

Liu Feng is not a professor at Peking University at all. He used this title only for the convenience of cheating. He belongs to the Peking University Institute of Private Economy, which I am familiar with, and is just a money-circulating organization similar to a school-run factory.
