The third exercise is Separate Heaven and Earth in English, a pretty far cry from the Chinese: tiáo lǐ pí wèi dān jǔ shǒu. Tiao is harmonize or reconcile; li is put in order; pi is spleen; wei is stomach; dan is single or sole; ju is yet another word for lift or hold up. Hold up one hand to harmonize spleen and stomach, in other words.
In this one, one hand is raised, palm up, and the other extends down, palm-down. Then the upper hand is spirals down and the lower hand spirals up along the centerline of the body. At about stomach level, the hands pass, the rising hand palm-up, lowering hand palm-down as in the video by Faye Yip, at about the four-minute mark.
Exercise four has a charming English name: the Wise Owl Gazes Backwards. The Chinese is wǔ láo qī shāng xiàng hòu qiáo, which when I look up each word comes out to something like “five work seven upwards towards behind look.” Rashka translates as “Look backward to eliminate five fatigues and seven illnesses.”
Sink down with both arms lowered, both hands facing back. Then open the arms to the left rotating the hands and arms all the way outward, so palms face up as shown.
Also turn the head all the way to the side. Notice that Master Yip does not turn at the waist. This is a stretch of the neck. Keep the head upright and suspended. Return to starting position. Repeat on the other side. Do both sides four times, alternating.
