the experience to the clinic Bob seemed to be nervous and he often became angry these days.so he came to the traditional Chinese doctor this morning.the doctor asked him some questions and also felt his pluse.then the doctor said to Bob that he has too much yang.the doctor advised him to eat some yin food like tofu and others,then he can keep out of the disease.So this is traditional Chinese therapeutics,don't you think it is kind of marvolous?
