Hello, where is Longbei? Generally speaking, the back can be divided into three parts, namely our upper focus, middle focus and lower focus. The upper jiao is the reflex zone of our heart and lungs, the middle jiao is our internal organs, and the lower jiao is our kidney and reproductive system. You can judge this.
Or because of the exuberant oil secretion, mostly because of our physical reasons, you can start from these aspects and take some Chinese medicine or Chinese patent medicine to adjust.
