Where can I buy an old calendar of Jigong?

The first thing I want to tell you is that if you take a medicine for seven to eight years, it is definitely not a good medicine, because if the symptoms of expectoration and asthma can be cured, they will be cured within a period of time, and you won't have to take medicine all the time. Just like our side, common bronchial diseases can be cured within 1-4 months. I suggest you stop looking. If you really want to treat diseases, you can consider learning about our Chinese medicine treatment, which also happens to be in Guangdong. This is also a kind of fate.
