The teacher of TV Yangshengtang is not necessarily real. Some health programs will invite some non-health or medical professional actors or celebrities to play experts to improve the attention and entertainment of the programs. In addition, some health programs may exaggerate the effects of certain foods or health care, or provide some inaccurate or unscientific health care methods, which may mislead viewers or listeners and even have a negative impact on their health. So the teacher of TV Yangshengtang is not necessarily true.
