On the first day, I mentioned that after practicing at night yesterday, I felt my head was empty and dizzy. The same happened after practicing at noon today. I felt something was wrong and asked senior brother Sun Yinxuan.
Family members, I have been practicing Yangyuan Technique for two days recently. It is indeed quite effective for the internal organs, viscera, and spine, but after practicing, my head feels empty and very uncomfortable. How should I solve this?
You are too eager to achieve results. You reached the spine level in just two days; are you rushing?
Because the spine feels quite uncomfortable, I went ahead to practice there first 
Slow is fast. Now that you have rushed ahead, your qi is not fully nurtured. Taking from the east wall to repair the west wall, what’s the point?
It has become quite clear now. Next, I will continue to focus on the internal organs and viscera, and not rush the spine for now.
Practicing skills really requires a teacher. If I hadn’t asked, I most likely would have continued the previous practice method, and my head would feel empty after every practice session
