The following is taken from Baidu:

"health-preserving vitality pile"

The first is skyscrapers. Stand up straight, heel up, hands up. If this lasts for two or three minutes, you can get through the meridians of the whole body.

Then there is the Yangyuan style. Heel landing, legs slightly bent, knees not exceeding toes, hands holding chest, eyes slightly closed. Practice from 5 minutes in the early stage and stand until your legs are tired and hot. This can strengthen the whole body 12 meridians.

Finally, return the type. Straighten your legs and put your hands on your navel. First press counterclockwise, then press clockwise, more than 36 times at a time. This can maintain vitality, make qi and blood belong to Guanyuan point and Qihai point, and preserve them.
