Hello, why do some people say that Mr. Ni Xiahai is a liar? I benefited a lot from watching his video. Thank you for your answers!

Hello! I didn't watch Ni's video, but I think since I have benefited from you, I shouldn't care too much about other people's opinions. First, you just learned the knowledge or truth of being a human being in the video, which may lead you in a subtle way.
