The pericardium mainly transports water, and the bladder meridian and kidney meridian mainly drain water. If you want to divert water downward, you must keep the pericardium, bladder and kidney channels unobstructed. Generally, the pericardium meridian mainly massages Zhongshan or Qu Ze, the bladder meridian mainly massages Kunlun, and the kidney meridian mainly massages Taixi. If you find obvious pain points, you can naturally draw water downwards to eliminate waste liquid and keep healthy.
