　「Training wings and standing」as a fledgling chick preparing to fly off repeatedly after short rest periods, or, trying again tomorrow, or, simply to stand upon as set of newly no-longer-integrated and bound feet as「concubine in training with swelling, palming and spurting」:「Bound feet…became a prerequisite for finding a husband, as well as an avenue for poorer women to marry into money. Women, their families, and their husbands took great pride in tiny feet, with the ideal length, called the 'Golden Lotus,' being about 7 cm (2.75 inches) long. …The process was started before the arch of the foot had a chance to develop fully, usually between the ages of 2 and 5.」

　「Concubine, service provider in training with swelled erection」indicates the same action will FOLLOW DURING THE NEXT DAY. Also refers to the NEXT TIME BLOCK IN SEQUENCE as the present, such as used by the shaman for billing purposes, but today may refer to a time period much longer than a client session, such as the next day, next week, next month, next year, etc.
　As for what might occur the NEXT MORNING AT DAYBREAK:「Rapid eye movement sleep (REM sleep) is a normal stage of sleep characterized by the rapid and random movement of the eyes. …REM sleep in adult humans typically occupies 20–25% of total sleep, about 90–120 minutes of a night's sleep. REM sleep is considered the lightest stage of sleep, and normally occurs close to morning. …Subjects' vividly recalled dreams mostly occur during REM sleep. …Erections of the penis (nocturnal penile tumescence or NPT) normally accompany REM sleep. …In females, erection of the clitoris (nocturnal clitoral tumescence or NCT) causes enlargement, with accompanying vaginal blood flow and transudation (i.e., lubrication). During a normal night of sleep the penis and clitoris may be erect for a total time of from one hour to as long as three and a half hours during REM.」
