The teacher is very angry with Professor Chen's name. A person who has studied health preservation for more than 30 years has cured the incurable diseases of his family and relatives in his own way. He came to participate in the program, claiming to have brought a "endangered" stunt, which can be "effective on the spot" for middle-aged and elderly diseases. Subsequently, a Chinese medicine practitioner questioned that the man was suspected of "practicing medicine without a license". Feng Wan was very angry at the scene and quarreled with Professor Chen in the program.
