Is Chen Jiekuan a disciple of Ni Gaohai Mansion?

Yes, his family is an ancestral Chinese medicine practitioner. Although he is Ni's disciple, he is anti-Ni in many places, and he pays special attention to taking the pulse. It is true to pay attention to the pulse condition, but there is no need to ridicule those who only pay attention to the syndrome. Japanese experts in Confucian classics, such as Dongdong, sometimes don't need to feel the pulse at all, but only need some certificates to treat diseases.
