Who is the person mentioned by Ni?

Liang Dong and Xu Wenbing were mentioned. When Ni recorded "The Cinema of China Academy of Sciences" in Beijing and Liang Dong, a banquet was held for Ni in the luxury apartment in Beijing. I think Ni is a man with strong masculinity who dares to say and do. Xu Wenbing and Tony Xia Hai have the same view on some diseases, food and drugs.
