I asked chatgpt about this exercise, and answer is interesting
Some qigong schools (like Shaolin, Daoist, or Wudang) have developed a “Five Lao Seven Injuries Qigong” (五劳七伤功) or “Five Lao Seven Injuries Back Exercise”, designed to restore spinal flexibility, balance qi flow, and heal back pain caused by these imbalances.
Typical characteristics:
- Slow spinal rotations and bending
- Gentle stretching of the lower back and waist
- Coordinated breathing (inhale through nose, exhale through mouth)
- Focus on Dantian (lower abdomen) and Du meridian (spinal energy channel)

Example routine (simplified)
(From traditional qigong interpretations — not medical advice)
1. Warm-up: Relax shoulders, stand with feet shoulder-width apart.
2. Inhale → Raise both arms slowly, feel the spine lengthen.
3. Exhale → Bend gently backward, feeling the “back qi” rise along the spine.
4. Inhale → Return upright, rotate waist left-right.
5. Exhale → Fold slightly forward, letting the spine relax and the head hang.
6. Repeat 7–9 times.
