I recommend you to stand on the health stake of Dachengquan. According to your high blood pressure, I suggest you put the ball in your abdomen with both hands (it was put on your chest).
Staying piles should be done step by step and cannot be forced, because you are not fighting, but keeping in good health. At first, you can stand for 5- 10 minutes, and you can stand for many times every day, and then you can stand for one minute every day, and you can stand for 1 hour for two months.
Regarding the detailed theory of standing piles, I recommend you to read the book "Scientific Standing Piles", which is well written. There should be one online.
Besides standing piles, we should also adjust our living habits and pay attention to the daily health care of hyperlipidemia and hypertension.
